LONDON - British Prime Minister David Cameron on Sunday slammed Britain's likely exit from the European Union (EU) as a "gamble of the century," warning the risks of leaving Europe to the country's trade, jobs and security.
"It's simply not good enough to assert everything will be all right when jobs and our country's future are at stake," Cameron wrote in an article published by the Sunday Telegraph newspaper.
In the article, he urged Eurosceptics to set out a vision outside the EU, describing the offer of Brexit as "a leap in the dark."
The prime minister asked those who want to leave the EU to sort out what relationship Britain would have with Europe in terms of trade, jobs, security and Britain's role in the world.
Cameron said the reconstructing a new relationship after Brexit would face "huge amounts of uncertainty" and would have an impact on investment and trade as well as on jobs and family finances.
On security, he argued that Britain currently has a whole set of arrangements with its European neighbors, and asked the "out" campaign to spell out "how they intend to keep people safe."
In the article, he also demanded that Eurosceptics to answer "the bigger question about our role in the world" outside the EU.
Cameron insisted European countries have to work together to deal with international threats, including the migration crisis, extremism and terrorism.(Xinhua)
