Met at the Gates of Downing Street

Now here is an interesting snippet from Sam Coates.

Gordon Brown is meeting Barack Obama at Downing Street on Saturday after the Presidential candidate has finished Breakfast with Tony Blair and then will meet David Cameron

Sam takes up the story

Number 10 were told by Obama's advisers that one plan under consideration was that the presumptive Democrat nominee would leave Downing Street and meet David Cameron at the gates of Downing Street. They would walk - yes walk - to Parliament for their meeting. Huge "spontaneous" photo op.
Though this plan was extremely risky for both sides and always seemed unlikely - Downing Street were terrified that this would be seen as a sign of Obama preferment. Which it would. The plan has now, apparently, been bashed on the head after high level intervention.
