LONDON — Britain’s main opposition party announced Sunday that it backs the UK’s staying in the European Union’s single market and customs union during a ‘‘transition period’’ after Brexit, arguing that would give much-needed certainty to businesses and consumers.
The Labor Party says the ruling Conservative Party’s Brexit position — taking Britain out of the EU single market immediately after March 2019, when Britain formally leaves the bloc — would be unnecessary and a highly risky path to take.
Labor Brexit Secretary Keir Starmer said his party wants Britain to keep abiding by the terms of its current EU membership during a transition period before a final shift to a new Britain-EU relationship.
He says that should avoid a ‘‘cliff edge’’ situation for the British economy. He did not specify how long this transition period should last.
