Boris Johnson has been called to step down as Prime Minister following reports of a Downing Street gathering during 2020's lockdown.
Police are in contact with the Cabinet Office over claims a senior aide to the Prime Minister organised a "bring your own booze" party in the garden behind No 10 during England's first lockdown in May 2020.
A leaked email shows 100 Downing Street staff were invited, of whom 40 are thought to have attended - including Boris Johnson and his wife Carrie.
England was under tough coronavirus restrictions banning groups from meeting socially outdoors when the message was sent.
Number 10 has refused to comment - citing an ongoing investigation.
Former Lib Dem leader and Christian MP, Tim Farron told Premier he is "genuinely appalled" by the Government's actions and the mockery it has made of Covid restrictions.
He said: "At Christmas 2020 there were hundreds of 1,000s, if not millions of people who spent Christmas alone.
"Doing it because we were told it was to keep ourselves safe, to protect the NHS and to protect the safety and wellbeing of others. And the people who gave us those instructions, it turns out, we're not just having parties, they're having loads of parties...when for the rest of us mere mortals, we were only allowed to meet one other person distanced in a park."
In order for justice to be done, Farron believes Boris Johnson should be held to account and step down as Prime Minister.
"It is just so outrageous, such a failure of leadership, and such a mockery of the people that our leaders are meant to lead.
"I really feel this has to lead the resignation of the prime minister."
These sentiments have been echoed by a number of politicians including former Conservative attorney general Dominic Grieve who has called Mr Johnson a "serial liar".
While there have been public cries of anger and upset over the gathering, Farron explains how Christians can respond in light of the Gospel.
"We need to be ready to forgive at all times. We need to be permanently repentant about our own sin. We need to be careful that we're not being hypocrites. And in our anger, we must not sin - this doesn't mean we shouldn't be angry.
"If something is unjust, then it is right to be angry with it. And we should demand justice. God demands justice, and the cross is that place where justice and mercy meets.
"It will be a very sorry world if because we're all sinners we just thought 'oh well, because we're sinners too we'll just let him get away with it.' I think it is right to insist that there is justice. We do believe there's right and there's wrong. And when it's clear cut, we shouldn't be sloppily neutral about it."
The-then culture secretary Oliver Dowden used a Downing Street press conference on the day of the alleged "bring your own booze" event to remind the public they could "meet one person outside of your household in an outdoor, public place, provided that you stay two metres apart".
The Government has stated that the PM "takes this matter very seriously" and repeated that an investigation is taking place which will include the gatherings on 15 May and 20 May 2020.
"It will establish the facts and if wrongdoing is established there will be requisite disciplinary action taken", Paymaster General Michael Ellis told the House of Commons on Tuesday.
