LONDON—British Prime Minister Boris Johnson said on Sept. 14 a bill that would break international law by breaching parts of the Brexit divorce deal was needed because the European Union hadn't taken a "revolver off the table" in trade talks.
Johnson accuses the EU of threatening to use the withdrawal treaty agreed in January to put up trade barriers between mainland Britain and Northern Ireland, and even to impose a food blockade, the latest brinkmanship of a four-year saga since Britain voted narrowly to leave the bloc.
The EU says Johnson's plan would wreck trade talks and propel the United Kingdom toward a messy Brexit. A derivatives industry source said on Sept. 14 the European Commission had delayed a decision on euro clearing, ramping up the pressure.
As Britain's House of Commons began debating the Internal Market Bill, which the EU has demanded London scraps by the end of September, Johnson said the bloc had shown in talks it was prepared to go to extreme and unreasonable lengths.
He said the bill would stop the EU using part of the Brexit divorce deal relating to Northern Ireland as leverage by threatening to block exports from elsewhere in the UK to the province.
Growing RebellionHowever, Johnson, who has a majority of 80 in the lower house of Parliament, is facing a growing rebellion from lawmakers in his Conservative Party.
All of Britain's living former prime ministers have expressed concern about his plan.
His previous finance minister, Sajid Javid, said he couldn't support the bill unless it was amended.
"Breaking international law is a step that should never be taken lightly," Javid said in a statement. "Having carefully studied the UK Internal Market Bill it is not clear to me why it is necessary to do so."
Conservative lawmaker Rehman Chishti, who was Johnson's special envoy for freedom of religion, quit his role over the issue while Johnson's former Attorney General Geoffrey Cox, who is influential with colleagues, was also critical.
"No British minister should solemnly undertake to observe treaty obligations with his fingers crossed behind his back," Cox said in The Times newspaper.
The leader of the opposition Labour Party, Keir Starmer, who was self-isolating due to a possible coronavirus case in his household, said he would oppose a bill that broke international law.
Johnson's plan to explicitly break international law has plunged Brexit back into a crisis less than four months before Britain is finally due to leave the EU's orbit at the end of a transition period.
Who Blinks First?British ministers say the bill, which explicitly states that it could be inconsistent with a host of international laws, is intended to clarify ambiguities—particularly over Northern Ireland—and act as a safeguard in case trade talks fall.
But some EU diplomats believe London is playing a game of chicken, inviting the collapse of trade talks to either get the deal it wants or leave without a deal.
The EU says it can't trust those who break agreements and that if the bill isn't effectively scrapped there will be no trade deal to cover everything from car parts to food.
If, as expected, it is passed in its second reading on Sept. 14, there will be four more days of debate on the bill's fine print—lasting into Sept. 22.
The main battleground could then be an attempt by one Conservative lawmaker to amend the bill to ensure any attempt to breach the Brexit divorce agreement receives prior approval from Parliament.
