Mr Singham claimed a new Conservative leader can turn negotiations around with “an incredibly aggressive approach” which will require “nerves of steel”. He argued that Britain should pursue an assertive pro-free trade policy after Brexit to maximise prosperity. However for this to happen he recommends MPs approve Theresa May’s EU exit deal, warning if they don’t “Brexit only gets softer from here”.
Speaking to Express.co.uk Mr Singham suggested: “An incredibly aggressive approach.
“It will require cojones, nerves of steel, because you’ll have to face up to the European Union.
“You’ll have to draw down a lot of leverage against them and you’ll have to be prepared to if necessary threaten to sue them.
“All kinds of things will need to be done and I think if they are done then we have a shot at a successful result”.
‘Cojones’ is a slang word for ‘balls’ used by South American Spanish speakers.
Mr Singham currently runs the International Trade and Competition Unit at the Institute of Economic Affairs.

A prominent Brexit advocate he has been termed “one of the world’s greatest economic thinkers” by former US National Security Advisor John Poindexter.
Mr Singham argued top EU figures have been complicating the Brexit process in a bid to persuade the UK to remain a member.
He asserted: “Part I think of the European Union’s strategy, of the Commission’s strategy, was to make this process as difficult as possible so that the British people would be demoralised.
“So that at the end of the day they’d throw their arms in the air and say it’s all too difficult, we can’t leave the EU, we’ll just stay.
“And I think that’s part of an orchestrated campaign that has been going on behind the scenes ever since the referendum.”
To combat this Mr Singham called for a new Conservative leader, once Mrs May’s deal is approved by Parliament.
