Britain's pullout from the European Union was marred by chaos on Sunday as Prime Minister Theresa May faced a potential plot by ministers to oust her and parliament was preparing to wrest control from the government.

In one of the most important shifts in the history of the country since the Second World War, the British political scene is undergoing a heated struggle over this. It is still not clear about three years after the 2016 referendum on how to get out of the EU. Will happen from the ground up.

In the meager and debilitating situation that Mai faces, the ministers insisted that she and the British government were still responsible for the country, and that the best view was and still was to pass the exit agreement, reached by May with Brussels, which was rejected by lawmakers twice.

With hundreds of thousands of people marching in central London on Saturday to demand another referendum on the exit, May was exposed to what the Sunday Times described as a "coup" by senior ministers seeking to overthrow it.

The newspaper reported that 11 unnamed senior ministers agreed that the prime minister should step down, warning that she became a harmful and isolated personality and her judgment and assessment of things was "foolish."

When asked by British finance minister Philip Hammond about the Sunday Times reports and other newspapers about a plot against Mai and whether it was in a difficult situation, Sky said: "I do not think so."

Hammond said the best option to move forward was for the parliament to back the May agreement, but said MPs might veto it, forcing parliament to try to find a way out of the impasse.

"I realize that we may not be able to get a majority of the prime minister's plan to get out of the EU, and if that's the case, the parliament will have to make a decision, not only on what he rejects but also on what he supports."

Environment Minister Mike Goff expressed his "absolute" support for May, adding that it was time for "calm" to focus on getting MPs to agree to the deal.

"I think it is not time to change the captain of the ship. I think what we should do is draw the right path, and the prime minister has charted the right path by reaching an agreement that respects the result of the referendum," he said.

The Sunday Times reported that the actual May deputy, David Ledington, is one of the candidates to become prime minister temporarily, but others are pressing for the post of Environment Secretary Geoff or Foreign Secretary Jeremy Hunt.

"I do not think I have any desire to replace the prime minister, and I think she is doing a great job," Leidington told reporters outside his home.

Parliamentarians are scheduled to discuss a government memo on Monday, saying the parliament is considering May's March 15 statement detailing the government's next exit steps, including a plan to seek to postpone it.
