According to President of the European Council Donald Tusk and President of the European Commission Jean-Claude Juncker, the EU is ready to "double efforts" in the talks if the Brexit transition period is extended. They noted, however, that Brussels would not agree to any changes to the deal.
"The [European] Commission can confirm that, like the United Kingdom, the European Union does not want this provision to enter into force", the letter signed by the EU politicians read.
In the meantime, Manfred Weber, a leading MEP with the centre-right European People's Party and candidate in the upcoming European parliamentary elections, urged British MPs to support the agreement negotiated by the government.
"We invite our British friends to accept this offer", he told reporters
The parliament is set to vote on a final Brexit agreement on 15 January. However, the prime minister does not have enough votes, as the opposition Labour Party and even some Conservative lawmakers have decided to oppose her deal.
