Donald and Melania Trump’s historic second state visit to Britain has ended – but not without generating more than a few headlines.

From multiple anti-Trump protests attended by thousands of Brits, to several royal events set up for the United States President, it was a busy few days for a select group of the world’s most powerful.

Several iconic images of the Trumps’ time in England have emerged, and social media has done its thing with the memes and the commentary.

Below are some of the most talked-about moments of the visit.

Melania Trump’s disappearing act

While Melania Trump’s fashion is often the centre of attention, the US First Lady seemingly disappeared into the background behind her wide-brimmed purple hat as she viewed items with her husband and the King and Queen at Windsor Castle.

The internet had a field day.

She matched her headwear with a grey Dior suit. The hat dwarfed the burgundy headpiece worn by Catherine, Princess of Wales.

Trump and the ‘beautiful’ Princess

A candid moment was caught between the Princess of Wales and Trump as King Charles gave a speech during the state banquet at Windsor Castle.

What the Princess was thinking about only she will know – but that hasn’t stopped social media from speculating.

Earlier, Trump appeared to call the Princess “beautiful” as he arrived in Britain.

Marine One delivered the President to Windsor Castle, where he was greeted by Prince William and Catherine.

The Independent reported that Trump told the Princess, “You’re so beautiful, so beautiful”, as he shook her hand.

He greeted Prince William with similar warmth, referring to him as “my friend”.

‘Deny Trump’

While the British royal family rolled out the red carpet, the country was not united in that sentiment.

Protesters took to the streets, many in orange face paint, to express their displeasure at the unwelcome visitor.

Images of the US President and convicted sex offender Jeffrey Epstein were projected on to Windsor Castle.

Four men have been arrested on suspicion of “malicious communications following a public stunt in Windsor” and are in custody, Thames Valley police said.

Pomp and circumstance

There was indeed plenty of pomp and circumstance throughout the visit, with the British royal family pulling out all the stops for the Trumps.

Fashion is always a talking point at royal and political events – and this one was no exception.

The Princess of Wales and the US First Lady were spotted stepping out in matching Ralph Lauren outfits. Whether it was co-ordinated effort to show unity or a mere coincidence, we may never know.

But Melania left some questioning her outfit choice for the Royal Banquet when she stepped out in a bright yellow off-the-shoulder Carolina Herrera gown. Some royal fans deemed it less than appropriate for a guest of honour at a white-tie banquet.

“That yellow dress on anyone ... could not be more inappropriate. It’s a state dinner not a night club. So embarrassing,” one person wrote in the comments of the photo shared by The Royal Family on Instagram.

“Off shoulder at a state dinner??? WTF? Didn’t they get a briefing???” someone else questioned.

Meeting with Keir Starmer

After their royal engagements, the Trumps met British Prime Minister Sir Keir Starmer and Lady Victoria Starmer at the Prime Minister’s country residence in Chequers.

Deals were signed, hands were shaken, and the four even had time to watch Army parachuters.
