CNN News:英国议会就脱欧协议进行投票

Which of these international organizations was formed in 1993? The European Union, the North Atlantic Treaty Organization, the League of Nations or the United Nations. The most recently formed organization here which was established in 1993 is the European Union.
And that brings us to the other government we mentioned earlier — the Parliament of the United Kingdom, because it's lawmakers are voting on a proposal to leave the European Union. No country's ever done that before but British voters chose to in 2016, in a referendum called the Brexit — the British exit from the EU. Through a long and complicated process, the government of British Prime Minister Teresa May reached a Brexit agreement with European officials. But Britain's Parliament has to approve it first. And a lot of lawmakers oppose the deal.

In fact, what's called the "meaningful vote" on the deal was originally scheduled for December 11th but because it looked like parliament was going to reject it at that time, the vote was delayed until this Tuesday. Prime Minister May has been working to shore up support for the agreement. Her political opponents have been speaking out against it. If parliament rejects the deal, Britain is still scheduled to leave the EU on March 29th, but what's called a "no deal Brexit" could lead to a lot more uncertainty and instability surrounding Britain's departure from the European Union.
So officials from around the world are closely watching what happens in Europe today.
