Just over two months after he stepped down as British Prime Minister, David Cameron announced today his resignation as a Member of Parliament.

Cameron's political career has been sliding down after his failed anti-Brexit campaign -- that is, in preventing Britain from delisting itself at the European Union.

From one of the world's most influential leaders, his political career tumbled down after the Brexit Elections in June.

He relinquished his post to Theresa May last July 13 with the mantra "Brits don't quit,". But 61 days later, he informed Parliament for Witney of his resignation “to start building a life outside Westminster.”

While his announcement sparked wave of condemnation from rival groups, his partymates expressed support to his decision, while posting their in their social media accounts.

British PM Theresa May said:

Boris Johnson, Secretary of State for Foreign and Commonwealth Affairs, said:

For his part, fellow MP George Gideon Oliver Osborne said:

Daniel John Hannan, another member of European Parliament, said:

In a statement, Cameron said he has been contemplating the decision since summer and pointed out that yielding his MP post was "the right thing to do."

"There’ll be a by-election, I’ll give the Conservative candidate my full support but in my view with modern politics, with the circumstances of my resignation, it isn’t really possible to be a proper backbench MP as a former prime minister," he said.

"I think everything you do would become a big distraction and a big diversion for what the government needs to do for our country. I support Theresa May, I think she’s got off to a great start, I think she can be a strong Prime Minister for our country," he added.

May is currently overseeing the process of Britain's exit from the E.U.

"I don’t want to be that distraction. I want Witney to have a new MP who can play a full part in parliamentary and political life without being a distraction," the former Prime Minister pointed out.

"I’m going to go on living locally, I’ll go on supporting local causes and the local charities that make this such a great place in our country," he added.
