A significant victory: Tory majority of more than 60

Despite polls suggesting the Tories could secure a landslide majority of more than 150, Theresa May would be satisfied with a majority of more than 60.

It would give her sufficient sway to implement her manifesto and see off opposition within her own party. The rump of pro-EU Tory MPs that remain would find their voice significantly diminished.

Ministers, however, have said that they would be disappointed with a majority of less than 80. They have privately expressed dissatisfaction with the way the campaign has been run.

Jeremy Corbyn, the Labour leader, has indicated that he will stay on regardless of the result which could lead to a renewed leadership challenge.
