British Prime Minister Rishi Sunak has hailed his deal on post-Brexit trading arrangements for Northern Ireland as a “decisive breakthrough”.

The agreement, named the Windsor Framework, changes the Northern Ireland Protocol, which was signed by Mr Johnson and came into force in 2021.

Under the agreement, Goods from Britain destined for Northern Ireland will travel through a new “green lane”, with a separate “red lane” for goods at risk of moving on to the EU

Products coming into Northern Ireland through the green lane will see checks and paperwork significantly reduced, while red lane goods will still be subject to normal checks

A “Stormont brake” allows the Northern Ireland Assembly to raise an objection to “significantly different” EU rules which would apply in Northern Ireland
