Donald Trump's £1.2million 'Beast' limousine is back on the streets of the UK as the US president joins other world leaders for the Nato summit today.
The heavily armed Cadillac One, part of the huge motorcade and multi-million pound security operation, has again rolled through the capital ahead of his meeting with world leaders at the Grove country house hotel in Hertfordshire.
Trump today flew to the summit in the Marine One helicopter before climbing in to the seven-seat black limousine as he made his way to the venue.
The enhanced limousine is at the centre of a 20-strong team of vehicles in a ring of steel of armed police and snipers watching the President's every move.
It is the second time the bomb-proof vehicle has been in Britain this year, after Trump's three day state visit in June, which involved more than 6,300 officers, which cost the Met Police £3.4million.
The presidential motorcade, which includes two identical limousines, one being a decoy with the same number plates 800-002, are transported ahead of the president's arrival on United States Air Force aircraft.
Trump's generation of presidential car debuted in 2018, but the Secret Service and the vehicle's designers have remained tight lipped on the details of the car's security features.

It weighs approximately nine tonnes (20,000lbs) with an eight inch thick armour-plated doors and bulletproof windows made up of five layers of glass and polycarbonate, and is reported to have tear gas grenade launchers, night vision cameras and a satellite phone.
The Cadillac has Kevlar-reinforced tyres and steel rims that can keep the vehicle moving even if the tyres have been destroyed. The bodywork of the car is five inch thick military grade armour. It is constructed of a combination of steel, titanium, aluminium and ceramic, in order to break up any projectiles.
It is believed to be equipped with a Duramax diesel engine. The reason it runs on diesel is because the fuel has a low volatility, which reduces the likelihood of it exploding.
The car can hold at least seven people and has a wide range of medical supplies on board, including bottles of the president's blood type are carried on board in case of a medical emergency.

The passenger cabin is said to be sealed, to fend off a chemical attack, while special foam would surround the fuel tank in case of impact.
