LABOUR MPs rate Theresa May as a much more impressive Westminster performer than their own leader Jeremy Corbyn, a new survey reveals.

Not one of the 40 Labour MPs questioned for the annual assessment of parliamentary impact found their leader a strong presence at the Commons dispatch box while more than a third of them, 35 per cent, spoke highly of Mrs May.

The only non-MPs on the list of the most impressive parliamentarian were Scots with Nicola Sturgeon, who came in at 10th spot, receiving four per cent and having got the votes of one Tory and three Labour MPs.

Scottish Conservative leader Ruth Davidson and the SNP’s Mhairi Black both received one per cent; the same level as Mr Corbyn, who was voted for by - a Tory MP.

Overall, the survey of 101 cross-party MPs saw David Cameron come top with 26 per cent with Mrs May close behind on 25 per cent.

Conservative backbencher Jacob Rees-Mogg was placed third on 13 per cent while Angus Robertson, the SNP leader at Westminster, came joint fourth on nine points with fellow Scot Michael Gove, the former justice secretary. Alex Salmond received five per cent.

Tony Blair was cited as impressive by 60 per cent of Labour MPs surveyed when he stood down as prime minister in 2007.

Ben Page, chief executive of Ipsos Mori, which conducted the survey, said: "The latest results from our annual survey of MPs are frankly unprecedented.

"Never before has a party leader received such low ratings from fellow MPs but it is not surprising given the difficulties Jeremy Corbyn has had with the parliamentary Labour Party."

The survey was conducted in June and July and involved 51 Conservative MPs, 40 Labour, six SNP, and four from other parties. In total, there are 650 MPs.
