A last-minute poll released the day before Britain goes to the polls has Theresa May’s Conservatives winning the largest victory since Margaret Thatcher was prime minister.

The poll by ComRes for The Independent has the Tories winning 44% of the General Election vote compared to Labour’s 34%, enough for a majority of 74 seats.

The result is a more favourable one for Conservative supporters than most other polls – a ‘poll of polls’ found Mrs May’s party defeating Labour by an average of seven points.

If correct, ComRes’ poll, a survey of 2,051 adults conducted this week, would give the Conservatives 362 seats, an increase of 31 on their current majority.




Labour would lose 20 seats and be left with 212, while the Liberal Democrats and SNP would also lose seats.

However, the results of other polls had Mrs May winning with a smaller majority.

The poll also showed where voters preferred Mrs May, and in which ways they believed Jeremy Corbyn is a better candidate to be prime minister.

When given a choice between the two, 51% said they would be relieved if Mrs May won, and 55% said they would be worried about Brexit negotiations in the event of a Labour win.

However, 51% said they would be more concerned for their family’s future under Mrs May’s leadership, while respondents were split 50-50 when asked whose victory would leave them feeling delighted.

The outcome of the vote is set to hinge on the turnout of 18 to 25-year-olds, who largely support Labour as a demographic.
