Social media images, which surfaced on Sunday, show the office of Robert Largan, MP for High Peak in Derbyshire, painted repeatedly with the word “Lies”. It comes as Boris Johnson was reportedly questioned by Sue Gray over the so-called “partygate” claims as part of her inquiry into the alleged gatherings.
Other MPs say emails of complaints have flooded into inboxes.
On Wednesday, the Prime Minister admitted to Parliament that he had attended a Downing Street social gathering while the country was still in its first lockdown.
The “socially distanced drinks” in the Downing Street garden on May 20, 2020, first came to light last Friday, when former Downing Street adviser Dominic Cummings posted a blog claiming that he had urged Mr Johnson to not let the event go ahead.
ITV News was later given an image of an email invitation from Martin Reynolds, the Prime Minister’s Principal Private Secretary, to over 100 members of staff, as well as Mr and Mrs Johnson.

At the time, the UK was still in its first nationwide lockdown.
Government guidance at the time stated people could meet “where the gathering is essential for work purposes – but workers should try to minimise all meetings and other gatherings in the workplace”.
Speaking to the House of Commons at Prime Minister’s Questions, Mr Johnson said he had spent about 25 minutes at the event, so that he could “thank groups of staff” for their hard work.
The Prime Minister claimed that he had thought at the time that the gathering had been a work meeting.
Mr Largan – who was part of the Conservatives’ 2019 intake of MPs – expressed his dismay about Mr Johnson’s admission to constituents.
In a letter last Wednesday, also shared on social media, he told one constituent: “Following the Prime Minister’s statement today, it is clear that breaches of COVID-19 restrictions took place in Downing Street.
“I will not defend the indefensible. We cannot have a situation where it is one rule for politicians and another rule for everyone else.”
He added: “I can assure you that I will be taking the appropriate action to defend integrity in public life.”
Several backbenchers have already been known to have submitted letters of no confidence to the 1922 Committee.
Robert Syms, the Tory MP for Poole, told the Telegraph that he was considering joining a growing number calling for the Prime Minister to step down.
He said: “I’ve had emails from what I would call Christian, decent, honest, honourable types of Tory voters, who say they feel embarrassed about voting Conservative with Boris Johnson.”
One Tory elected in a former Labour Red Wall seat in 2019 said: “I don’t know which has been worse: the hundreds of emails, the members resigning or the fact that it has just been ridiculed.”
Another Tory MP told the paper: “We have had an influx of emails over the past 48 hours. People are very, very angry.”
A third said: “I think there’s genuine anger. And I don’t blame people – I’m angry about it as well.”
