The UK has begun to prepare for Donald Trump's state visit to Windsor by building a 'ring of steel' to protect the US president.
Pictures have emerged of metal fences being constructed at strategic locations in the historic royal town as the King prepares to host both Trump and his wife Melania.
The multi-million pound police operation is on high alert as it comes just days after the assassination of the US president's close ally Charlie Kirk at a university in Utah.
Thousands of British police officers will be on duty throughout the two-day visit from September 17 to 19, where the guests will be feted with a ceremonial welcome and state banquet.
More than 100 US Secret Service agents are expected to accompany the president, alongside MI5 agents who are monitoring potential lone-wolf attackers and underground political opponents.
