Britain's influence in the European Union will be stronger if it votes to remain in the bloc in a June 23 referendum, Prime Minister David Cameron said on Sunday, according to Reuters. In an interview on BBC television, Cameron - whose "In" campaign has been branded as scaremongering by pro-Brexit supporters for warning of the risks of quitting the 28-nation EU - highlighted the advantages of staying. "If we wake up on June 24 and we are in, Britain's authority within the EU will be stronger," he said. "No other country has done what we have done, hold a renegotiation (for improved EU membership terms), hold a referendum and then people will know that the British agenda ... is going straight to the top." "If we vote In, I think there will be actually a wall of investment," he said. "Companies that are responsible for employing people in this country and making things in this country will want to do more, employ more, make more ... if we vote out, it is a decade of uncertainty."
