I had always planned to write an account of my trip there as for me it was a wonderfully surreal experience. One I will cherish.
In no way, do I aim this to come across as "Ohh how cool am I?". Big headed I am not (actually I'd benefit from being a bit more "I can do"). It's probably of very little interest to anyone actually, I simply want to reminisce over the visit and diaries, supposedly are a good way to document our fun times. If Adrian Mole can have his diaries, then I see no reason I can't. If you are interested in reading further, then hopefully I can share with you the surreality of this day.
Country bumpkin goes to the big city....
About two and a bit weeks before the meeting, I spoke on the phone with the person at the company I work for who was co-ordinating the project. I knew at the time a project with the British government was under discussion, but not the specifics.
When speaking on the phone with my colleague he said to me something along the lines of (I'm paraphrasing as I don't remember the exact wording), "Phil, it'd be really good if you could help out. In fact, we're having a meeting about it soon and it'd be good if you could join us". I remember thinking at the time, "Great (in a "man, not again! way"), that means another trip down to London!" I had not long been down for another work project and wasn't fussed about going again any time soon. So I replied with "And the meetings in London is it?" (thinking, please say no!)....The conversation continued.
Colleague: "Yeah, it's at Number 10".
Me: [insert mini cardiac arrest]
Me: "Errm, Number 10....you mean, like Downing Street, Number 10? As in Number 10 Downing Street?"
Colleague: "Yep!"
Me: (and I remember saying this) "Yes! OK, well I best buy some new socks then!"
So, that was that, I was going to get to go to Number 10 Downing Street (and in the process, acquire some much needed hole-less socks!) Then another few days later, I saw the invite pop onto my calendar "Number 10 meeting". A few days after that, e-mail confirmation from another colleague who'd be attending saying "So your name is in the database" with a copy of the e-mail sent to a man who's domain name had @no10 in it!

On to the actual day itself then....
Well actually it began the afternoon before because as the meeting was the following morning and I live far enough away from London that a reasonable journey is required, I thought it best to go down the night before -- especially for a meeting of such significance! So, after pottering around in a hotel room, I headed for bed knowing I'd need to be bright eyed and bushy tailed for the next day's fun!
A good nights sleep in a London hotel is not an experience to be expected and this night was no different. But it was enough and I awoke ready for my adventure.
The meeting was to begin at 11.45am, although for security checks etc we were advised to get there around 11.30am. The four of us going from the company arranged for a last minute pre-meet at our offices nearby at 10.30, giving us 30 mins to go over what we'd discuss, and then plenty of time for the 1.3 mile walk to Downing Street.
Here is our route.

I remember that the weather on that day was particularly warm (if you've ever been in London on a hot day, you'll know it's not pleasant). Me being all dressed smart did not aid the cooling either.....shorts and t-shirt would have been much more preferable, though less acceptable for the occasion. Also, I had my one pair of "smart shoes" on - I had not worn these for years (I avoid having to wear a shirt and/or tie and the shiny shoes that go with them at all costs!) and coupled with the heat, the lack of "re-wearing them in" (it's a phrase, don't worry!) and the mile and a bit walk up to Downing Street, I could feel they were ripping my feet to shreds. I can still recall the rubbing sensation I felt on the back of my heal. Anyway, relatively un-flustered we arrived at the front gates to Downing Street....
As expected, security was very tight - this is the home to the head of her Majesty's government after all.

As you can see, there are two set of gates - the lower outer barrier and the main gates. Armed police in numbers are highly visible - and you are meant to see them and their weapons.
Upon arrival, we showed our ID to the police officer manning the side gate who checked that our names were on the list and that this matched with the identification presented to him. I remember thinking the experience wasn't too dissimilar from when you see people queuing up outside an exclusive nightclub. If the guy on the door sees your name on the list, you're in! This was much the same.
Aside from how surreal this felt, I was consciously aware of all the tourists outside. As a popular London tourist destination, I myself have stood outside the gates taking photos, secretly hoping that at any moment a motorcade will rush in or out of the gates carrying a senior official or member of the royal family. Not including hoping to catch glimpse of a VIP, one will often see a number of visitors walking in and out of the gates. Who are they? Why are they here? What are they doing? Is it a senior member of the secret intelligence service coming to brief the Prime Minister on a situation in the Middle East, or someone coming to measure up for new curtains? On this occasion I was one of those people (more curtain fitter than spook though!), and knowing people are looking at you thinking "Who is he?" is a remarkably strange experience - I suppose a useful one for someone like myself who could do with a bit more confidence!
Upon gaining entry to Downing Street, you go straight into a "security cabin". In fact, the makers of the cabin have images of the actual box on their website. Basically they (several heavily armed officers from the Metropolitan Police Service's Protection Command) just run your stuff through a scanner - much like the ones at airports and check all is in order. Nerves were beginning to get the better of me so I had to release some of it by making a small joke. I just said "Well I hope our flights not delayed" (and hoped they wouldn't shoot me!). Once given the all clear, we're then officially onto Downing Street, perhaps one of the most famous streets in the world? I had seen this street thousands of times on the TV - probably every day on the news in fact and here I was on this very street. Surreal! It's actually somewhat of a cocoon - protected from London's hustle and bustle. A small piece of serenity in this vibrant nest of craziness.
Myself and my colleagues then walked towards what is arguably the most famous door in the world - the black door which interestingly can only be opened from the inside (i.e. there is no keyhole). Of a slight note of humour to me, because the weather was warm on that day, the door was open (I suppose an intruder having got this far is not likely to be stopped by any door anyway!). The ever faithful policeman who stands guard over the door permitted our entry into the entrance hall of 10 Downing Street (what the hell was I doing!!!).
Another policeman (yeah I've lost count by this stage how many I've seen!) checks us off the list again, and we have to hand over any electronic equipment such as phones, cameras etc.
We were then shown through to a room where other people attending the meeting were gathered and shortly after we were herded into the meeting room.
The inside of Number 10 is huge! A maze of stairs and corridors led us to a lavish room which looked perfect for a banquet, fit for a king (or a Prime Minister). The room where the meeting took place was the The State Dining Room. This is the room where all formal state dinners are held, and the room from which the Prime Minister gives his monthly press conference. A virtual tour of the room is available on the Number 10 website, here.
Now time for a little anecdote from the meeting.....I decided that the technological souvenir I wanted to take from my time there (for some reason, no psychologist as of yet has been able to interpret its meaning!) was knowing I could, upon departure from Downing Street update my Facebook status saying I'd used the lavatory at Number 10. I did, and this moment in history was documented here;

Sadly, I did not get to use his actual bathroom and did in fact use a rather grotty one, presumably used by cleaning staff. I then couldn't easily find my way back to the meeting room....but I made it back and continued with the meeting in question.
Once the meeting had finished, the PM's special advisor kindly guided us back through the maze and down the Grand Staircase back towards the entrance hall where we had begun. Strangely enough, the only thing I can remember about that part is picturing the scene in the film Love Actually where Hugh Grant, as the Prime Minister dances down the staircase (not that they used the actual one) -- and don't worry, I didn't reenact the scene -- far too many people with guns around!
Ah, looks like that clip is unavailable. Try this one!
We collected our phones and cameras (yes, we got the obligatory "outside the famous black door" shot!) and set off back to the office. Our surreal mid day meeting at 10 Downing Street was complete!
What a fun day!

Faces are blurred for privacy of course, but don't worry, I'm in it!
