Prime Minister Theresa May’s Brexit bill suffered a second defeat at the House of Lords after the lawmakers rejected last week an amendment with regard to the rights of the people of the European Union who are staying in the United Kingdom. Yesterday, by an overwhelming majority, 366 to 268, the lawmakers voted in favor of an amendment which gives the parliamentarians in the United Kingdom, the final say over the Brexit deal, which is expected to be reached over next two years after the Article 50 is triggered before March 31st this year.

The amendment was introduced by the Labor Party of the UK but the government had argued that it would be a threat to national interest. However, that didn’t prevent the amendment from securing a bipartisan victory. While Ms. May had verbally promised a vote to the parliament in her Brexit speech, the amendment binds her to make good on that promise.

The Brexit bill will now return to the House of Commons with the amendment forcing May to have a vote on her Brexit deal and another guaranteeing the rights of EU citizens. The government is working hard to pass the bill and trigger the Article 50 divorce clause by March 31st or the exit would become more difficult after that date. From April 1st, a country looking to exit the EU would need the support of 14 members of the 27 members group.
