The European Union's second Brexit delay could go on until 30 March, 2020, an official with the bloc said, as 27 national envoys were preparing for a leaders' summit on Wednesday that is due to decide on the matter, Reuters reported.
Earlier in the day UK House of Commons approved the plan of Prime Minister Theresa May to postpone the withdrawal from the European Union to 30 June from 12 April.
Meanwhile, according to a spokesman for Prime Minister Theresa May's Cabinet, talks between the UK government and the opposition Labour party to reach a compromise Brexit deal on Tuesday were productive, the sides agreed to continue negotiations on Thursday.
May has planned to present her compromise agreement with the opposition to the heads of EU countries at the European Council summit on Wednesday in order to reinforce UK request for postponing Brexit from 12 April to 30 June.
However, the leaked note from the meeting has revealed that the remaining EU members look more and more ready to consider an up to nine-month extension, also creating a "mechanism" to keep an eye on London's Brexit progress, the Guardian newspaper reported on Tuesday.
After the United Kingdom failed to agree on the Brexit deal by the initial March 29 deadline, Brussels extended the deadline until April 12 in a bid to give UK lawmakers more time to find a way out of the Brexit deadlock or leave without a deal.
However, UK parliament has so far failed to reach a consensus on the withdrawal arrangements but passed a law effectively obliging May to seek another Brexit delay with Brussels to prevent a no-deal Brexit on Friday.
