The European Commission (EC) will allocate a package of measures for Britain to ease transferring goods to Northern Ireland.
Meanwhile, the EC abruptly stopped the improvements of trading rules which London has been demanding since after the Brexit.
The measures of the EU executive are enacted to ease customs control, including food clearance and transferring medicine.
However, it will renegotiate the protocol which governs the unique trading position of Northern Ireland, thus potentially damaging relations between Brussels and London.
Commission vice-president in charge of EU-UK relations, Maros Sefcovic, will present the plans to EU member states on Wednesday.
It will also set out further plans to involve more people in the British province.
Co-chairman of Britain’s ruling Conservative Party, Oliver Dowden, said Britain would fully engage with the EU on the proposals.
“We will look at them and engage properly with them,” he told Sky News.
He also added that a fundamental change is important to this protocol.
Ireland’s PM, Micheal Martin, said that the EU listened to worries about the protocol and was trying to solve issues.
Britain and its government ought to be part of the solution too. “It takes two to tango,” he added.
Ireland: the best of both worlds
After the proposals, Supermarkets can supply the stores in Northern Ireland with meat products from Britain.
Sausages and other chilled meat products are banned from entering the EU, including North Ireland.
Northern Ireland remained part of the EU’s single market while staying part of the UK.
Consequently, the exports of Ireland face no restriction, customs or tariffs.
Sefcovic said this allows the businesses in Northern Ireland to enjoy the best of both worlds.
British sausages will enter Northern Ireland, under the commission’s plan, if intended for Northern Irish consumers only.
“That’s our proposal. We’ll put it on the table, and if it’s rejected, then we have a problem,” Sefcovic said.
