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.
