EU Agriculture Commissioner Phil Hogan said Britain's credibility would be seriously undermined if it "gave up" its promise to pay the 39 billion pound divorce bill. Asked about the possibility that Britain leaves the EU without an agreement and without paying the exit bill, Hogan told Politico: respecting or implementing the commitments already made.

"This has already been accepted by the governments of the United Kingdom and the European Union and I see no way to increase the credibility of a third country by effectively giving up the financial commitments of the regulation of the European Union. divorce contained in the withdrawal agreement. "

The Hardline Brexiteers urge Theresa May to pay the entire bill only if Brussels shows the firm intention to conclude a generous commercial agreement.

£ 39 billion was approved in December 2017, after the Prime Minister announced in a speech "honoring" the commitments made earlier.

In his keynote address in Florence in September 2017, the Prime Minister said: "I do not want our partners to be afraid of having to pay more or receive less for the rest of the current budget plan as a result of our decision to leave. .

"The United Kingdom will honor the commitments we made during the period of our membership."

It is believed that Brussels would need this sum to reach an agreement on the EU budget in October.

Mr Hogan, who is currently in Sydney to discuss free trade with Australia, said: "We have taken into account the fact that 12 billion euros less are available for the overall budget of EU from the UK leaving the European Union.

"We have integrated all the necessary financial scenarios."

And the EU seems ready to receive full payment, even in case of Brexit without issue.

In a statement issued in January, the European Commission said: "All the commitments made by the 28 Member States should be honored by the 28 Member States.

"This is also true in a non-agreement scenario, where the UK should continue to meet all the commitments made when joining the EU."

Mr Hogan also confirmed intensive preparatory talks in Brussels to prepare the EU27 for a "no agreement" scenario.

He said: "We are going to discuss with the British authorities at the appropriate time ways of simplifying the requirements of the United Kingdom, where they are self-sufficient only 60% in food."
