Election 2017 polls latest: Will Jeremy Corbyn replace Theresa May as Prime Minister?
A new Survation poll shows that Labour has slashed the Conservatives lead from 17 points to just one point over the course of the past month.
In contrast, the latest ICM poll the Conservatives lead slipped from 12 points to 11 points in the space of one week.
The big differences in the polls are due to different estimates of turnout among young people more likely to vote Labour.
Most pollsters still believe that Theresa May is on track to get a majority but it may not be as large as she once hoped.
One YouGov projection has predicted that the Conservatives are on track to lose their majority, leaving Britain with a hung parliament.
According to the Times, one Whitehall source said: “A senior civil servant sat in a meeting and said, ‘We’ve just all been told to prepare our plan for a hung parliament.”
Speaking in Edinburgh on Monday, the Prime Minister warned that if the Conservatives lose six seats then the Tories will not get a majority on June 8.
She added: "That means Jeremy Corbyn in Number 10 and Nicola Sturgeon pulling the strings from Bute House."
But even if there was a hung parliament, Labour are still unlikely to have enough seats to form a minority government or coalition.
It is not impossible that Mr Corbyn could become Prime Minister but it would be one of the biggest surprises in the history of British politics.
The most likely scenario is the Conservatives forming a minority government by attempting to govern alone without a majority.
But Mrs May has repeatedly warned that there could be a "coaltion of chaos" between Labour, the Liberal Democrats and the SNP.
