Mr Cameron, who is no longer a Conservative MP, warned against tax rises as he defended his own austerity policies, telling US broadcaster CNN: “Today we do face very different circumstances.
“So piling, say, tax increases on top of that before you’ve even opened up the economy wouldn’t make any sense at all.
“I think it’s been right for the Government here in the UK and governments around the world to recognise this is more like a sort of wartime situation.”
