LONDON - The British Prime Miniter Boris Johnson has set a five-week deadline for the UK and EU to reach a post-Brexit agreement.

He said that a no-deal departure would be a “good outcome” for Britain that would allow the country to “prosper”.

The Financial Times reports that the UK is planning new legislation that would override the Northern Ireland Protocol, a key part of last year's EU withdrawal agreement.

However, according to Boris Johnson’s official spokesman, the British government is committed to its Brexit withdrawal agreement with the EU despite reports it was preparing to breach it.

A report in the Financial Times today claimed that Johnson would bring forward legislation on Wednesday that would include clauses, pertaining to Northern Ireland, which would override the UK’s EU withdrawal agreement.

The Prime Minister’s official spokesman said today that the government wanted to make some “minor clarifications” in the internal market legislation and that the Prime Minister was committed to the withdrawal agreement.

The changes would only come into place if the UK left the EU on a no-deal basis at the end of the year.

Northern Ireland will remain in a customs union with the EU after the end of the post-Brexit transition period on 31 December, while Great Britain will not.

This means that some goods will require checks and customs declaration forms when going between Great Britain and Northern Ireland.

The proposed clarifications revolve around goods that are deemed to be “at risk” of entering the EU’s single market, after they are sent from Great Britain to Northern Ireland.
