British Prime Minister David Cameron urged politicians to support what is in the best interest of Britain after the pound plummeted to the biggest one-day loss since 2010. The fall of the currency resulted from speculations of the British exit from the EU after popular London mayor Boris Johnson declared his support behind the exit.

“I am not standing for re-election, I have no other agenda than what is best for our country,” the News Corp quoted Cameron telling a packed parliament.

Cameron’s defence of the EU membership received more support from the opposition Labour Party and Scottish National Party than from his own which stands broadly divided on the issue.

“British jobs and British business depend on being able to trade with Europe on a level playing field,” the Spectator quoted Cameron as saying. “So we wanted new protections for our economy; to safeguard the pound; to promote our industries – including our financial services industries; to protect British taxpayers from the costs of problems in the Eurozone and to ensure we have a full say over the rules of the single market while remaining outside the Eurozone. And we got all of those things.”

He added that the responsibility of maintaining the financial stability of UK will be with the Bank of England and that the British taxpayers will not be required to bail out any country in the Eurozone.

“We have made sure that the Eurozone cannot act as a bloc to undermine the integrity of the free trade single market,” he said before the parliament. “And we have guaranteed that British business will never face any discrimination for being outside the Eurozone.”

While Cameron has been able to procure the support of most of his senior cabinet colleagues, six members of his own party said they would campaign for an exit, which underlined the deep differences in opinions over Europe since the days of Margaret Thatcher.
