Theresa May is more popular with voters than any leader since the late 1970s, a new poll shows as another reveals Jeremy Corbyn is more unpopular than ever.

Almost two in every three voters (61 per cent) believe Mrs May would make the most capable Prime Minister compared with about one in four (23 per cent) who said Mr Corbyn.

Mrs May’s score of 61 per cent is the highest recorded by the polling company Ipsos Mori since it started asking the question in 1979.

Meanwhile, a separate poll conducted by YouGov shows that with just six weeks to go until June 8 Mr Corbyn has a net favourability rating of minus 42 - his all time low.
