Earlier in the day, deputy chief EU negotiator Sabine Weyand said that the EU was open to “alternative arrangements” to the Irish backstop.
A source in May’s office told Reuters that the prime minister had asked lawmakers to support a proposal that would replace the Northern Irish backstop listed in the Brexit deal with another arrangement.
In January, the UK House of Commons rejected the Brexit plan that was presented by Prime Minister Theresa May after months of negotiations with the European Union.
