Theresa May suffers crushing defeat over Brexit deal

British Prime Minister Theresa May's Brexit divorce deal was defeated by a crushing margin in parliament on Tuesday, further complicating the country's historic exit from the EU and triggering a no-confidence motion against her government.

May's bid to get the Withdrawal Agreement, struck between London and Brussels, through a House of Commons was defeated by a margin of 202 to 432 - a majority of 230, the biggest defeat ever suffered by a British premier in modern history.

Within minutes after the defeat, opposition Labour leader Jeremy Corbyn announced that his party would move a motion of no-confidence against May's government, to be held on Wednesday.

Britain is set to exit the 28-member European Union, which it joined in 1973, on March 29. With just over two months to go until the scheduled departure, Britain is still undecide on what to do.

Hardline Brexiteers and Remainers opposed the agreement for different reasons. Many feared that Britain could lock itself into an unfavourable trading relationship with the European Union.

Over 100 lawmakers of May's Conservative party - both Brexiteers and Remainers - overwhelmingly voted against the deal, leading to the worst parliamentary defeat for a government in recent British history.

The crushing defeat also marks the collapse of her two-year strategy of forging an amicable divorce with close ties to the EU after the March 29 exit.

Following her defeat in the House of Commons, May said that the MPs have established what they are against but not what they are for.

"The house has spoken and the government will listen. It is clear that the house does not support this deal but tonight's vote tells us nothing what it does support.

"Nothing about how, or even if, it intends to honour the decision the British people took in a referendum parliament decided to hold," she said.

"I ask members on all sides of the house to listen to the British people who want this matter settled and work with the government to do just that," she added.

Moments after the outcome in parliament, Corbyn submitted a motion of no-confidence in May's government, calling her defeat "catastrophic".

"Labour will table a motion of no-confidence in May's government tomorrow," he said.

According to the Britain's parliamentary procedure, when a bill is rejected by the MPs, the prime minister has three sitting days to return to Parliament with a Plan B.

It is expected that May would head to Brussels on Wednesday to try and secure further concessions from the EU before coming back to UK Parliament with a new proposal.

This could be put to vote by the MPs. Should this also fail, the Government would have another three weeks to come back with another alternative.

If the withdrawal agreement never gets through with Parliament, then in all likeliness the UK will crash out of the EU without a deal on March 29.

This would mean overnight EU laws and customs and the free movement of goods, services and people will cease.
