Britain will only pay its EU divorce bill if the bloc agrees to the framework for a future trade deal, the new Brexit secretary warned in an interview published Sunday.

Dominic Raab, who replaced David Davis after he quit the role earlier this month in protest over the government’s Brexit strategy, said “some conditionality between the two” was needed.

He added that the Article 50 mechanism used to trigger Britain’s imminent exit from the European Union provided for new deal details.

“Article 50 requires, as we negotiate the withdrawal agreement, that there’s a future framework for our new relationship going forward, so the two are linked,” Raab told the Sunday Telegraph.

“You can’t have one side fulfilling its side of the bargain and the other side not, or going slow, or failing to commit on its side. So I think we do need to make sure that there’s some conditionality between the two,” he said.

Doubt cast

Prime Minister Theresa May agreed in December to a financial settlement totaling £35 to £39 billion ($46-51 billion, 39-44 billion euros) that ministers said depended on agreeing on future trade ties.

But Cabinet members have since cast doubt on the position. 

Finance minister Philip Hammond said shortly afterward that he found it “inconceivable” Britain would not pay its bill, which he described as “not a credible scenario.”

The country is set to leave the bloc on March 30, but the two sides want to strike a divorce agreement by late October in order to give parliament enough time to endorse a deal.

Raab met the EU’s top negotiator Michel Barnier for the first time on Friday, where he heard doubts over May’s new Brexit blueprint for the future relationship.

But Barnier noted the priority in talks should be on finalizing the initial divorce deal.

May’s plan unpopular

A hard-line stance by the British government on the financial settlement could complicate progress, with Raab insisting on the link with the bill and a future agreement.

May’s plans formally unveiled in early July envisions a customs partnership for goods and a common rulebook with the EU.

It has faced severe criticism in Britain, including from within her own Cabinet and Conservative Party.

Former foreign secretary Boris Johnson and Davis both resigned in opposition.
