Andy McSmith's Diary: Tipsters always fall short of running naked down Whitehall

The pundit and publisher Iain Dale has finally come up with a lame excuse for not keeping the most famous promise he ever made. On election night in 2010, Dale poured scorn on a BBC exit poll that predicted the Liberal Democrats would win as few as 59 seats. If that proved true, Dale promised, he would “run naked down Whitehall”. Actually, the poll overestimated rather than underestimated Nick Clegg’s appeal. They won 57 seats.
