Spearheaded by adviser Dominic Cummings, The Times has reported the Cabinet will be trimmed from 33 to 20 next year. Although Mr Johnson did undertake a smaller reshuffle in the wake of the election, some within Whitehalld have labelled the upcoming cull as the "Valentine's Day massacre". On Friday Mr Johnson's Brexit deal was passed in the Commons, 358 to 234. With the deal now receiving the backing of Parliament, Mr Johnson stated the UK was now "one step closer to getting Brexit done".
Within his Brexit deal, Mr Johnson included a provision to stop the Government from extending the transition period.
Moreover, the withdrawal agreement has also done away with any legislation deemed "not to serve a purpose" while also giving UK courts more power to reconsider rulings made by the European Court of Justice.
Speaking on the deal, Mr Johnson said: "It ensures we depart on 31 January.
"At that point Brexit will be done. It will be over."
Jeremy Corbyn, however, stated Brexit had "paralysed the political system".

1.37pm update: SNP MP booed
SNP MP, Kirsten Oswald was booed during an appearance on the BBC programme, 'Any Questions?'.
The MP was booed after she suggested Boris Johnson had no majority to deliver Brexit in Scotland.
She said: "I have to tell you the Tories do not have a majority in Scotland.
"The Tories had a terrible night in Scotland – they lost more than half of their MPs. The SNP have secured 80 percent of the MPs in Scotland and we’ve done that because we do not support Brexit.
"Scotland didn’t vote for Brexit, it didn’t vote for Boris Johnson and, most certainly, it did not vote for this cliff edge he is potentially going to be dragging us off against our express will.
"From the point of view of Scotland, which voted substantially to remain in the EU, that is what we want to do. We do not want Brexit, this is not for us."
