Lib Dems on the run
So much for Liberal Democrats not believing in first past the post.
Their activists might have spent a lifetime trying to ditch the current system for electing MPs. But having lost the referendum over the Alternative Vote earlier this year, they appear, on the basis of their athleticism at least, to be embracing the system we've got.
I joined about 30 activists for the conference run this morning. A 5km blast of exercise along the canal banks and streets of Birmingham. And there was plenty of competition to get across that finish line first.
Not that I was likely to trouble those setting the pace. Instead, it was a chance to grab a breathless word with Brian Paddick, the former senior policeman who is the Lib Dem candidate for Mayor of London next year, live on 5 live Breakfast. Whilst Rachel Burden was interviewing Nick Clegg on the BBC conference stand, I was huffing and puffing along the canal bank.
It turns out there are conference runs at the Labour and Conservative conferences too. I'll be turning out again - but who else will be packing their running kit?
