The Tories are losing ground to Labour according to a new poll
The Conservatives' lead has been cut to seven points, according to Opinium, who carried out a poll on May 30 and 31.
This marks a cut from a nine point lead indicated by their last poll, with just days to go before the general election.
However a second poll released at 6pm claimed the Tories had a huge 12 point lead.
The ComRes study put the Conservatives on 47 points and Labour on 35, a one point increase for both parties on previous polls by the group.
Despite this large lead, the poll revealed a signifant many more people believe Jeremy Corbyn has better policies for "people like me and my family" than Theresa May.
This section saw Labour on 44 and the Tories on 38.
YouGov, ICM, ORB and Survation will all be releasing polls results from 5pm onwards.
It comes after a YouGov election model released earlier today estimated the Tories will win 308 seats, 18 short of a 326-seat majority.
Labour are estimated to take 261 seats, up from 257 on Friday, increasing the possibility of a hung parliament.
Polls taken before the snap election was called by Mrs May indicated her party had a 20 point lead. All pollster are now indicating this has been cut dramatically.
However, Mrs May has repeated dismissed the apparent Labour surge, claiming on several occasions: "The only poll that counts is the one taking place on June 8."

Pollsters have defended the varied nature of their results.

“The question is what is the alternative? It's not clear there is one.”
He explained the way polls utilised expected voter turnout resulted in discrepancies across different companies.
He said: “The difference in the polls in this election is easy to understand – it is almost wholly to do with how pollsters treat turnout.
"Generally speaking, the polls that continue to show a large Conservative lead are those who are basing their turnout models on the pattern of turnout in 2015. Those that show smaller leads are basing turnout on how likely people say they are to vote."
