US President Donald Trump is going to be greeted with a spectacular royal charm offensive during his state visit this week.
The aim will be to dazzle and flatter him with the ultimate red-carpet experience, with guards of honour, flypasts, historic carriages, a lavish banquet, pomp and pageantry.
In return, Sir Keir Starmer will be hoping this gilt-edged reception will help to deliver the UK's message on awkward issues such as Ukraine and trade tariffs.
And if anyone can get the US president's attention and influence him, surely King Charles III and the Royal Family can.
But how will King Charles handle his sometimes unpredictable guest in Windsor? Can he be the Trump whisperer?
