UK Prime Minister, David Cameron has warned that Peace in Europe could be at risk if Britain votes to leave the European Union.
Mr Cameron said the UK had regretted “turning its back” on Europe in the past, adding that the EU had “helped reconcile” countries and maintain peace.
“Was leaving the union a “risk worth taking?”, Mr Cameron asked.
Meanwhile, Ex-London mayor Boris Johnson hit back, saying that the EU’s “anti-democratic tendencies” was “a force for instability and alienation”.
The Vote Leave campaign said: “During the renegotiation the PM said he ‘ruled nothing out’. Now he thinks leaving the EU would lead to war. What changed?”
Despite his security warning, Mr Cameron defended his decision to call the referendum that “You shouldn’t try to hold an independent sovereign nation in an organisation against its will.”
There are just over six weeks to go until the 23rd June referendum which would decide whether Britain remains in or leaves the EU.
The PM’s comments and a rival speech from Mr Johnson came as the referendum campaign intensifies, following last week’s elections.
Mr Cameron, who was introduced by former Labour foreign secretary David Miliband, argued that the EU with Britain had helped bring together countries that had been “at each other’s throats for decades”.
He warned that the peace and stability Europe has enjoyed in recent years could not be guaranteed, saying“the clock being turned back to an age of competing nationalism in Europe”.
While Europe has largely been at peace since 1945, Mr Cameron said it was barely two decades since the Bosnian war while, more recently, Russia has been at war with Georgia and Ukraine.
“Can we be so sure that peace and stability on our continent are assured beyond any shadow of doubt? Is that a risk worth taking? I would never be so rash as to make that assumption,” he said.
Mr Cameron argued “isolationism has never served this country well”.
