"We respect the decision of the UK Parliament, but we regret that the majority [of the lawmakers] did not support the agreement. We have repeatedly stressed that the United Kingdom's withdrawal from the European Union without a deal served no one's interests", Demmer said at a briefing.

On Tuesday, the UK Parliament rejected Prime Minister Theresa May's updated Brexit plan, agreed between the UK government and the European Union, by 391 votes to 242.
The UK Parliament has previously turned down May's Brexit plan in January, mainly due to concerns over the Irish border backstop. Later on Wednesday, the legislative body is set to hold a vote on a no-deal Brexit. If the lawmakers do not back this scenario, a vote on the extension of the potential Brexit deadline, initially slated for March 29, will be held on Thursday.
