Figures come just before the election campaign strides into its fourth week.
Prime Minister Boris Johnson began his rally for voters this week by visiting some of the areas in the north of England and knocking on doors in Mansfield.
He also went to Bolton, the scene of a high-rise fire, and sought to reassure residents about the Government's intention in dealing with cladding on buildings.
Labour leader Jeremy Corbyn has also been out drumming up support and visiting flood-hit neighbourhoods in the north.
Yesterday, he met with senior party figures to agree his manifesto with particular attention thought to be paid to the immigration policy.
The two leading parties continue to battle it out over the main policy areas this year including immigration, which the Tories will vow to cut and the NHS which Mr Corbyn has accused Mr Johnson of trying to sell off.
Meanwhile Lib Dem leader Jo Swinson is to continue her legal battle over the upcoming TV debates, with a letter due to be sent to the BBC who have arranged a head-to-head only between Mr Johnson and Mr Corbyn.
