Johnson is one of 11 lawmakers vying to run the world’s fifth largest economy after May resigned as leader of the governing Conservatives on Friday, having failed to unite parliament or the country behind her Brexit plan.
Britain is mired in its deepest political crisis in decades over how, when and whether it should leave the EU – a decision that will fall to May’s successor and affect both its future role on the world stage and prosperity for generations to come.
As the contest to replace May gathered pace on Sunday, Johnson made his first major intervention, targeting the large pro-Brexit wing of his Conservative Party with a promise to take a hard line with Brussels over the terms of Britain’s exit.
“I think our friends and partners need to understand that the money is going to be retained until such time as we have greater clarity about the way forward,” Johnson told the Sunday Times. “In getting a good deal, money is a great solvent and a great lubricant.”
Main rivals foreign minister Jeremy Hunt, agriculture minister Michael Gove and interior minister Sajid Javid, also want to renegotiate or modify the deal, but none have threatened not to pay the exit bill May agreed with the EU in 2018.
The 39 billion pounds represent outstanding British liabilities to the EU to be paid over a number of years.
The EU has repeatedly said it will not reopen discussion of the Brexit transition deal it reached with May last year, which British lawmakers have rejected three times, or to negotiate a future trade deal with Britain without the divorce payment.
Those three defeats forced May to announce her resignation.
“We will have a different attitude in the negotiating team and a different negotiating team,” Johnson said, adding that he would give personal orders to negotiators from his ministerial team rather than politically impartial public servants.
Johnson also said border arrangements with Ireland should be settled only as part of a long-term agreement, rejecting a negotiated “backstop” that would preserve the open border with Northern Ireland, a British province, but which Conservative lawmakers fear is a backdoor way of requiring Britain to continue to follow EU rules after Brexit.
Shortly after the Johnson interview was published he won the backing of pro-Brexit lawmaker Steve Baker, an influential figure in the party’s hardline eurosceptic wing.
Johnson, popular with Conservative grassroots members who will be given a choice between the final two candidates, first has to win enough support amongst elected Conservative lawmakers – where the depth of his support is less well known – to make it onto that shortlist.
Conservative members of parliament will begin whittling the list down this week with a series of votes in parliament.
Ahead of that, the leading candidates were out in force on Sunday setting out their thoughts on everything from Brexit and tax to drug-taking.
Gove, seen as one of the strongest challengers to Johnson, apologized for using cocaine 20 years ago. “It was a mistake, and it was a mistake that I deeply regret,” he told the BBC.
He set out plans to rip up rules on Value Added Tax – one of the country’s most lucrative sales taxes – and replace it with a simpler system. He also confirmed he would be willing to delay Brexit by a few days or weeks if a deal with the EU was close.
Britain’s original departure date was March 29 but that was shelved after May’s withdrawal bill was repeatedly rejected in parliament. The current deadline is Oct. 31.
Hunt did not commit to when Britain would leave the EU, but said it had to be with a deal, or else the country would face a general election in which the Conservatives could lose out to leftist Labour Party leader Jeremy Corbyn.
Javid, another candidate seen as having the potential to beat Johnson, set out his intent to reopen negotiations in Brussels by offering to pay hundreds of millions of pounds to cover the implementation of a new border system to smooth trade between Britain and Ireland.
