FORMER Prime Minister Tony Blair was in Harrow today and promises to ‘help out  in marginals’ during the final week of the election campaign. One simple question for this afternoon: Is Glenda Jackson going to let him on her marginal Hampstead turf?

She admits telling him after her re-election in 2005 that she felt the main opposition during the campaign had not been the Tories or the Lib Dems – but him!
