LONDON - Britain's opposition Labour Party said on Monday it would back calls for a second referendum on Brexit if parliament rejects its alternative plan for leaving the European Union.
With just over a month until Britain is due to leave the bloc on March 29, Prime Minister Theresa May is seeking changes to her exit deal in order to break an impasse in parliament.
Labour's decision could damage her hopes of winning support for a revised deal in a vote she has promised by March 12, by attracting those who would have backed her agreement in order to avoid a no-deal exit but who would prefer a second referendum.
Parliament is due to debate and vote on Wednesday on the next steps in Britain's tortuous departure from the EU, and lawmakers are set to offer proposals, or amendments, which could include demanding the exit deal is put to a public vote.
Labour said it would put forward an amendment calling on the government to adopt its Brexit proposals, which include a permanent customs union with the EU and close alignment with the bloc's single market.
