A Guardian/ICM poll puts the Conservatives at 46 percent, while Labour trails behind at 34 percent.
Although the figures fall short of suggesting a landslide victory, they nevertheless imply the Tory leader is set to win a majority of 96 seats in Parliament, sharply up from May’s working majority of 17 in the House of Commons before the election.
It would also be the party’s greatest majority since the days of former PM Margaret Thatcher.
“This final poll confirms the pattern that ICM has produced over the last fortnight: a fairly healthy and static Conservative share with consolidation of the Labour bump first witnessed after the manifesto publication,” said ICM’s Martin Boon.
A YouGov poll on Wednesday gave the Tories a more modest lead compared to the ICM survey, but it still put the Conservatives ahead of Labour by seven points.
“The seven-point Conservative lead is the same as at the previous election, but we think it is likely they will nevertheless be returned with an increased majority,” YouGov Director Anthony Wells said.
