A post-Brexit trade pact between the U.S. and U.K. will not receive legislative approval in Washington if Britain leaves the European Union in a manner that imperils a peace accord in Northern Ireland, U.S. House of Representatives Speaker Nancy Pelosi warned.
Pelosi, whose Democratic Party controls the lower house of Congress, said any form of Brexit should not jeopardize the Good Friday Agreement, including the seamless border between the Republic of Ireland and the U.K.'s Northern Ireland.
The Good Friday Agreement was signed by British and Irish governments in 1998, ending a period of conflict in Northern Ireland and establishing a devolved government for the territory.
"If Brexit undermines the Good Friday accord, there will be no chance of a U.S.-U.K. trade agreement passing the Congress," Pelosi said in a statement.
Pelosi issued the warning after U.S. National Security Adviser John Bolton said the U.K. would be "first in line" for a trade deal with the U.S. following Brexit.
Bolton suggested that the two countries could first pursue piecemeal, sector-specific trade deals before striking a wider bilateral agreement.
The U.K. is due to leave the EU on Oct. 31, but formal talks with Brussels have yet to resume. U.K. Prime Minister Boris Johnson has repeatedly pledged to deliver Brexit even without a withdrawal agreement in place.
