Prime Minister David Cameron warned Monday that a British exit from the EU would threaten peace on the continent, as the campaign for next month's crucial referendum gathered steam after regional elections, AFP reports.
With polls showing the two campaigns are neck-and-neck, Cameron and the de-facto leader of the "Leave" movement, former London mayor Boris Johnson, were both stepping up efforts to woo undecided voters.
Leaving the 28-member bloc in the June 23 referendum would be a "reckless and irresponsible" risk to Britain's economic stability that would leave it "permanently poorer", Cameron warned.
He also said a "Brexit" would threaten Britain's strength and security in the world, along with peace on the continent if "Europe's foremost military power" quit the European Union.
