Mr Bolton, speaking ahead of US President Donald Trump’s state visit next week, believes that securing Brexit would also allow NATO to become “more effective”. Speaking to the Daily Telegraph, the outspoken politician also backed Trump’s vow to negotiate with the UK to strike up trade deals beneficial to both countries once the exit had been completed. He recognised the difficulty that Brexit had created within the country but continued to maintain it was vital for it to get over the line.
Mr Bolton also said it was “critical that Britain retains its military strength”.
He told the newspaper: “We have agonised with you throughout this process.
“The US preference is for Britain to follow the course of what the people asked for and leave the EU. It is a lesson for everyone in the triumph of democracy.
“As a separate nation again, Britain’s impact on the world has the prospect of being even greater.

“And from the US point of view that is all to the good.
“I think it will help us in Nato in particular to have another strong and independent country that will help Nato to be more effective, and that has to be a plus.”
Mr Bolton’s comments come after Trump said he was preparing to announce he would be standing for a second term.
Trump won the election in 2016, outscoring rival Hillary Clinton and creating history with his stunning victory.
He tweeted that he would confirm his intentions, alongside wife Melania, Vice President Mike Pence and Second Lady Karen Pence on June 18 in Orlando, Flordia.
The President has cut a controversial figure after taking on the top post from Barack Obama.
His policies have ranged from the executive order which restricts entry to the US from certain countries, as well as the wall with Mexico and his rejection of the Paris climate deal.
These have resulted in heavy criticism internally in the US as well as internationally.
