Munira Wilson MP has challenged Conservatives in the House of Commons to dump Boris Johnson in a vote tonight.

The Twickenham Lib-Dem MP said: "Tonight is the moment of truth for Conservative MPs. They must do the right thing and sack Boris Johnson once and for all."

She added: "Too much precious time has already been wasted with internal squabbles in the Conservative Party, and we can't have any more of this nonsense.

"With a cost of living crisis at home and a war in Europe, we need strong leadership we can trust.

"This past weekend, the British public spilled onto the streets in a great show of patriotism to honour Her Majesty the Queen for her Platinum Jubilee celebrations.

"The Queen's unerring sense of duty sets an example for all of us. It is time to restore the same respect, integrity and sense of duty to the office of the Prime Minister."

Boris Johnson faces a confidence vote this evening against the background of law-breaking in Number 10, cover-ups and bad results in the local government elections.

The Conservatives were all but wiped out in Richmond with the result the party was left with just one councillor.

The pressure was turned up over the weekend after the Prime Minister was booed when arriving at St Paul's Cathedral by patriotic crowds celebrating the Queen's Platinum Jubilee.

It would need 180 Conservative MPs to vote against Johnson this evening to trigger a leadership contest. Critics appear to be hamstrung by a lack of an obvious replacement with Liz Truss the current favourite.

Former Health Secretary, Jeremy Hunt, has suggested he is keen to stand, while Trade minister Penny Mordaunt failed to offer Johnson support in a tweet.

Both the local MPs, Sarah Olney and Munira Wilson, have been calling for Johnson to go for weeks.

It is widely believed that Johnson will win the confidence vote this evening – with the result due to come in by around 8pm. However, depending on the scale of the rebellion, he could be fatally undermined.

Speaking last week, Sarah Olney, the Richmond Park MP, said Johnson's leadership 'has been an absolute disaster for this country'.

She said: "His self-indulgence and refusal to resign has hampered our ability to address the cost of living crisis and climate change. The longer he stays in post, the people of Britain suffer."

She said it may be that the longer Johnson stays in power the better it is for the Lib-Dems in winnable seats in the south of England. A number of Conservative MPs with small majorities in London and the South have signalled they have no confidence in the Prime Minister.

However, the MP said: "As a constituency MP I find it incredibly depressing. We have such poor governance and government in this country at the moment and it is creating real problems for my constituents."

Today, the Lib-Dem leader and Kingston MP, Ed Davey, said: "It's judgement day for Conservative MPs and their sleaze-ridden Prime Minister.

"If they fail to sack Boris Johnson, it will be an insult to all those who made sacrifices and suffered while he partied."

Lib-Dem councillor, James Chard, tweeted: "Wouldn't it be a lovely way to celebrate the Platty Joobs by giving Her Majesty the 15th Prime Minister of her reign?"

Sarah Olney MP said: "When so many people in Richmond Park are suffering from spiralling bills and a cost of living emergency, we can't have a Prime Minister just focused on saving his own skin.

"It is time Conservative MPs finally do their patriotic duty and sack Boris Johnson. Our country needs strong leadership and we can't have any more of this nonsense."

She added: "The Conservative party is wasting precious time with these internal squabbles. Families want to see an emergency tax cut, not a Westminster soap opera.

"If Conservative MPs had the courage and decency to act months ago when the rest of the country all knew Boris Johnson had to go, then we wouldn't be in this mess right now."
