Progressive voters have been driven away from Labour by a lack of argument and vision from Keir Starmer, according to a report using research from a senior pollster to Tony Blair and Bill Clinton.

Downing Street is understood to have been briefed on the research, which has also been handed to allies of the potential leadership candidates Andy Burnham, Wes Streeting and Angela Rayner.
