Donald Trump’s heavyweight eight-ton armoured Cadillac certainly lives up to its nickname, The Beast. So when the £1.2million limousine rolled into a BP petrol station in London this weekend, it was a fittingly conspicuous sign of the US President’s imminent arrival.

Security staff were filling up the heavily guarded car ahead of Mr Trump’s three-day state visit, which kicked off on Monday amid a slick £25million security operation.

The President, accompanied by his wife, Melania, touched down at Stansted Airport in Air Force One, one of two specially modified Boeing 747-200s.

The highly customised, luxurious aircraft feature 4,000 square feet of floor space, including a presidential suite with a large office and conference room, a medical suite that can be used as an operating room and two food preparation galleys that can feed 100 people at a time.

Accompanying the US leader on board were Mick Mulvaney, Mr Trump’s third, and acting, chief of staff, Sarah Sanders, his press secretary, Kellyanne Conway who helped lead his 2016 campaign and Dan Scavino, his head of social media, among others.
