Britain's embattled Prime Minister Theresa May hopes the declaration will convince sceptical lawmakers to approve her vision for the UK's departure from the bloc.
Extending transition is expected to cost up to £10billion a year in European Union subscriptions but is a possible way of avoiding using the controversial Irish border backstop.

Although a vote was not legally necessary - ratification is only needed in the European Parliament and the British parliament - Irish Prime Minister Leo Varadkar wanted to show that politicians from all sides supported his position, the report noted.
