LIZ Truss will today unveil legislation to rip up part of the Brexit deal in order to restore power-sharing in Northern Ireland.
The Foreign Secretary says the blueprint is needed to protect peace in the region.
But the EU warned of a trade war if Britain dares push ahead.
The plan lets the Government suspend parts of the Northern Ireland Protocol, which slaps checks on goods going between NI and GB.
Instead, two new channels of trade would be created.
A red lane would check goods heading to the Irish Republic — protecting the EU single market — while a check-free green lane will carry items to NI.

The DUP has refused to join a government in NI until the checks are ditched. It means power-sharing has collapsed.
NI Secretary Brandon Lewis said the plan is “lawful” and “correct”.
And a source close to Ms Truss insisted: “This is about doing the right thing for Northern Ireland.”
Last night The Daily Telegraph reported that under the plan European judges will not be allowed a final say on NI disputes.
