The Conservatives can win a 100-seat majority at the snap election, analysis by Britain’s most respected pollster for The Telegraph has suggested.

If current polling was replicated the Tories would win an estimated 375 seats – double the 189 seats Labour would pick up.

Prof John Curtice from Strathclyde University conducted the analysis and said Labour’s collapse under Jeremy Corbyn helped explain the results.

Labour marginal seats in the West Midlands, on the edge of Northern cities and in London suburbs are believed to be the most likely to fall to the Tories.

Conservative Party board members have told this newspaper they want “decapitation strategy” targeting Labour heartland seats in the North.
