The day Obama came to visit.

Over the past couple of days, President Obama has been in London. In his time here, he met the Queen, Prince Philip, Tom Hanks, David Beckham, Kate Middleton, Colin Firth and J.K. Rowling. A notable name missing from that list is my own, so I decided to pop to London yesterday to say 'hello'.

I went with a couple of friends from university - Michael and Mary. We got on the train with little idea of Obama's schedule for the day, as it didn't seem to be overly-publicised, probably for security reasons. The initial plan was to go on the Tube straight to Westminster, and watch the day unfold there. However, we were on the Underground when it emerged that Michael, being a Northerner, had never seen Buckingham Palace. We decided to get off at Green(e) Park, and walk across to the Palace. Coincidentally, our route across the park took us right behind Lancaster House, where there was a huge police presence, and helicopters overhead. Little did we know that we'd just stumbled upon the place where Cameron and Obama were holding their press conference. We peered through the fence for a minute, before a couple of horses shouted at us to move away.

The horses that told us to move.

We rounded the corner, and saw the Presidential motorcade on The Mall, complete with motorbikes zooming around, armoured Jeeps blocking the road, and the all-important 'Beast', Obama's car, somewhere in the middle.

We decided to hang around outside the Palace for the press conference to end, so we'd be able to catch Obama when he left. We wandered around for a bit, and noticed George Alagiah doing an interview for the BBC. The obvious thing to to was to stand around in the background, phoning anyone who was near a TV to tell them we were famous. However, upon phoning my brother, Ross, it turned out the BBC News Channel was focusing on the press conference in Lancaster House. Logical, I suppose.

George Alagiah himself. Highlight of the day.

Eventually, Obama and Cameron stopped talking, and the motorcade left Lancaster House, and turned onto The Mall. We got a good view of the car going past, and saw Barack waving in the back. He must get really bored or having to wave whenever he drives anywhere.

We then wandered through St. James' Park, past the numerous pelicans and tourists, to Horseguards Parade, then cut trough to Whitehall, and walked past Downing Street to get to Parliament Square. We knew that Obama was giving a speech in Westminster Palace at 3pm, so we wanted to get a good spot to see his car. Apparently, twice simply wasn't enough.

Security was tight, and the police were armed... with binoculars. (Mary's photo. She has a better camera than me.)

We were originally standing by the normal entrance to Parliament, when the police moved us out of the way to let Peter Mandleson through. It was then that we realised we were at the wrong gate - there was no way they were going to make Obama follow in Mandleson's tracks.

The bulk of the press photographers and film crew were standing opposite the Sovereign's Entrance, so we took a position amid them, and awaited our third sighting of the President and his entourage. As before, the police bikes sped past, stopping traffic, then the motorcade drew up and turned into the gate to Westminster Palace. We hadn't expected Obama to get out of the car, but one of the Secret Service agents opened the foot-thick door of his car and out stepped the President.

Checking to see if I had turned up.

The press photographers went into paparazzi-mode, shouting at everyone and everything, jostling people with their lenses, their shutters clattering away behind us. We weren't allowed to get too close, and my camera's not particularly good, but it was nice nonetheless to get a couple of photographs.

Overall, it was a good day out. Alagiah and Obama in one day has satisfied the celebrity-spotter in me for at least a couple of weeks.
