Lord Kinnock, the former Labour leader, has predicted his party will not win another general election in his lifetime ahead of Jeremy Corbyn’s expected coronation this week.

The peer, who defeated the hard-Left in the 1980s and put Labour on the road to modernisation that would sweep Tony Blair into power, said the party was facing the “greatest crisis” in its history.

He makes the comments in a BBC Panorama programme broadcast on Monday in which some of Mr Corbyn’s supporters warn of retribution against MPs who have opposed his leadership.
