Getting out of the single European market would be a "self-inflicted wound for Britain," Cameron said during the Sky News’s In or Out EU referendum program.
He stressed that the single market had a unified set of rules, and if the United Kingdom left the market, the country would lose the ability to shape the rules that determine the single market.
"I do think there are real risks for leaving. I do not accept it is scaremongering… I am genuinely worried about Britain leaving the single market," Cameron said during the Sky News’s In or Out EU referendum program.
The prime minster reaffirmed his commitment to UK's special status within the European Union, and said that in case of the United Kingdom leaving the bloc, it would take the government a decade to negotiate the trade arrangements in place.
