LONDON (Reuters) – The pound posted its biggest one-day loss in almost six years yesterday on concerns of a possible British exit from the EU, adding to the pressure on Prime Minister David Cameron as he mounted a defence of his deal to keep the country in the bloc.
The fall in the currency, as well as in government bond prices, was triggered by London Mayor Boris Johnson – a senior figure in Cameron’s Conservative Party – throwing his support behind the exit campaign.
Johnson, one of the country’s most popular politicians, gave the “Brexit” camp a much-needed figurehead when he announced his support on Sunday, just days after Cameron struck his deal in Brussels to hand Britain what he called a “special status”.
Cameron, addressing parliament to champion the deal as a good basis for Britain to stay in the EU, faced criticism from lawmakers in his divided party and exchanged barbs with Johnson, whose announcement had bitterly disappointed him.
The stakes are high in the June 23 referendum. A vote to leave would not only transform Britain’s future in world affairs but also shake the EU, which has struggled to maintain unity over migration and financial crises, by ripping away its second-largest economy and one of its main military powers.
Cameron called on politicians to campaign on what is best for Britain – in a veiled jab at Johnson, whose stance may be designed to attract widespread eurosceptic support among Conservatives in a bid to succeed Cameron, who has said he will step down before the next election in 2020.
“I am not standing for re-election, I have no other agenda than what is best for our country,” Cameron told a packed parliament. “I am standing here telling you what I think, my responsibility as prime minister is to speak plainly about what I believe is right for our country and that is why I will do every day for the next four months.”
He added: “We are a great country and, whatever choice we make, we will still be great, but I believe the choice is between being an even greater Britain inside a reformed EU or a great leap into the unknown.”
Both sides in the debate argue Britain would be financially better off if their cause succeeds.
Johnson, London mayor since 2008, defended his stance by saying those who argued Britain would not thrive outside the 28-member bloc were the same people who wanted the country to make the “catastrophic mistake” of joining the euro single currency.
