 Well, it's been almost six weeks since a damp Prime Minister, Rishi Sunak, announced the election in the pouring rain in Downing Street. Since then, the opposition Labour Party's polling lead has barely moved, with the party around 20 points ahead of the governing Conservatives. Unless something unexpected happens between now and Thursday, it looks as though Labour's Keir Starmer will be Prime Minister by the end of the week, with what looks like it could be a very substantial parliamentary majority.
