Boris Johnson is heading into the general election campaign with an average poll lead of 10 points over Jeremy Corbyn's Labour, data shows.

Figures from poll trackers which map the various opinion poll firms suggest the Conservatives are on 35 per cent, with Jeremy Corbyn on 25 per cent and the Lib Dems on 18 per cent.

The figures, based on polls conducted by 14 firms and carried out by Britain Election and the FT, will provide a boost to Mr Johnson as he heads into the December election, his first as Tory leader and Prime Minister.

A separate analysis this morning suggested that he is on course for a double-digit majority unless there is a surge in tactical voting.

His party has had a lead of up to 16 per cent in some recent polls but the wider analysis can suggest a more stable long-term trend.

Mr Corbyn might also be looking over his shoulder, where the Remainer Lib Dems are close to Labour than his party is to the Tories.

Leader Jo Swinson has adopted a hardline pro-Remain stance in the hope of stealing votes and seats from Mr Corbyn, whose party continues to attempt to appeal to both sides.

Boris Johnson is bracing for a 'mega-tough' election battle today - amid warnings he needs to win 50 Labour seats to offset losses to Remainers in Scotland and the South.

Mr Johnson will seek to rally his troops for the pre-Christmas showdown by attacking Jeremy Corbyn at what promises to be a brutal PMQs session in the Commons later.

The brutal clashes come as Tory strategists finalise their plans for an incredibly volatile campaign, where local factors are expected to play a pivotal role.

They are set to target 'Workington Man' - older, white, non-graduate male voters living in swing seats in the North of England.

Mr Corbyn (pictured leaving home today) might also be looking over his shoulder, where the Remainer Lib Dems are close to Labour than his party is to the Tories.

Analysis today suggested the PM is on course to win a Commons majority unless Remain voters work tactically to block a Tory victory and ensure an EU-backing leadership, according to research.

The Conservatives would achieve a majority of 44 if no tactical voting took place but anti-Brexit voters could scupper this, according to a study by the Best for Britain campaign.

If less than a third of Remain voters (30 per cent) used their vote tactically they could swing the election to deny the Prime Minister and to secure a Remain majority of four.

The research by the anti-Brexit campaign was based on seat-by-seat analysis of 46,000 people over September and October and was released on Wednesday, ahead of the expected approval of a December 12 election by the Lords.

If 40 per cent of pro-Remain voters worked tactically then they could return a majority of 36, reflecting their Brexit views, according to the research.

The study was carried out by the Focaldata polling agency using a technique known as multi-level regression and post-stratification, a method that reportedly gave a rare but accurate prediction that Donald Trump would become US president in 2016.
