New poll gives Labour astonishing six-point lead over the Tories after No10 party

Labour has opened up a six-point lead over the Tories as revelations over rule-breaking Christmas parties and sleaze hit Boris Johnson in the polls.

An exclusive survey, conducted by Survation on December 1, after the Mirror's bombshell story about No 10's lockdown-breaking festive knees-up, sees support for Labour soar to 40% (+1%) while the Conservatives slump to 34%.

It represents a breakthrough for Keir Starmer as it is the highest poll lead for his party since Boris Johnson took power.

The last time backing for Labour reached 40%, with the same pollster, was January 2, 2019, when Theresa May was PM and Jeremy Corbyn was at the Opposition's helm.

Ed Davey's Lib Dems polled at 10% (+1%), while right-wing populist party Reform UK, headed by Brexiteer Richard Tice, represents a new threat to the Tories, taking 3% (+3%). Backing for the Greens was also up at 4% (+1%).

Additionally, 48% of Brits surveyed believe the Government has worse standards than it had in previous years.

And 60% said the Tories do believe there is 'one rule for them and one rule for everyone else'.

It comes as the Prime Minister attempts to fend off a barrage of criticism over the secret festive bash on December 18 last year.

The Met Police has ruled out an official investigation into alleged breaches of Covid rules, but the PM has asked Cabinet Secretary Simon Case to "establish the facts".

Leaked footage of staff, including the PM's former spokeswoman Allegra Stratton, joking about "cheese and wine" at the bash and "definitely" no social distancing, however, sparked fresh public anger about the get-together.

Ms Stratton resigned on Wednesday after the video emerged.

Meanwhile, the Conservatives are battling to hang on to power in a crunch by-election in North Shropshire after Owen Paterson quit over repeated and "egregious" breaches of lobbying rules.

The scandal led to numerous allegations of Tory sleaze, with a string of MPs found to have lucrative second jobs as political consultants.

Mr Johnson was also forced to U-turn on his bid to rip up standards rules.

The Government could also be facing a backbench Tory rebellion over the PM's new plan B restrictions in Parliament next week.
