Interesting - and rather impressive.

I had lunch yesterday with a friend who had arrived at St Pancras early and sat down for a coffee.

A few minutes later a man sat down at the table next to him with his coffee and started working on his laptop.

"I'm going to vote for you" said my friend to David Cameron.

"Oh. thank you".

Far younger in the flesh, no sign of a minder or assistant, very friendly and nice.

Interesting.

I quite like Cameron - but his problem will be to balance the new forward-thinking Tories with the old (almost far-right) zenaphobic loonies.

Not easy !
