The British parliament on Monday rejected Prime Minister Teresa Mae's revised "BRICEST" agreement with the European Union to get out of the bloc, deepening the country's worst political crisis in decades just 17 days ahead of the planned EU exit.

Parliament voted against the revised agreement on May's "Precast" by a vote of 391 to 242 after its last-minute talks with union leaders on Monday failed to dispel the fears of its critics.

The leader of the British Labor Party, Jeremy Corbin, has called for a general election and has confirmed that his party will present a new plan for Britain's exit from the European Union.

In a quick reaction to the British public's decision, spokesman for European Council President Donald Tusk said yesterday that the British House of Commons' second rejection of the EU-UK agreement on its withdrawal from the EU had "significantly increased" the risk of going out "without agreement" .

"We regret the result of the vote," the spokesman said. The EU has done everything possible to reach an agreement. It's hard to know what we can do more than that. "

"While there is only 17 days remaining on March 29, the new vote significantly increased the likelihood of leaving the EU without an agreement. If the UK makes a logical request for an extension, the 27-nation EU will consider it and decide unanimously. "

The British Prime Minister said after the defeat that the vote to go out without an agreement will take place today, and if the parliament rejected the idea, will be the last vote to extend the process of Britain's exit from the Union on Thursday, according to the timetable set in advance.

Mae told parliament after the vote that she still sees the agreement she negotiated for Britain's exit from the EU on March 29 as "the best and only deal".

She vowed to vote today on a proposal for lawmakers to oppose leaving the EU without an agreement.

If legislators refuse, as expected, to go out without an agreement, May said another vote would be held tomorrow to demand parliamentary approval to seek an extension of Britain's exit from the European Union.

British Prime Minister Teresa Mae said her country had a last chance to break out of the EU naturally. In a speech to the House of Commons, May warned of dire consequences for the Council's vote against the revised BRICCET agreement.
