Gordon Brown is set to lead Labour into an election bloodbath so crushing it could take his party a decade to recover, according to the largest ever poll of marginal seats which predicts a landslide victory for David Cameron.
Eight cabinet ministers, including the Home Secretary and the Justice Secretary, would be swept away in the rout as the Tories marched into Downing Street with a majority of 146, says the poll, conducted for PoliticsHome.com and exclusively revealed to The Observer. Seats that have been Labour since the First World War would fall.
