Senior royals are expected to be called upon to join US President Donald Trump at a sumptuous state banquet held in his honour.

Traditionally, on the evening of the first day of a state visit, the visiting monarch, president or premier is feted with a lavish dinner.

Some 170 guests will gather for the meticulously-planned grand affair in the Buckingham Palace Ballroom in June.

But who from the Windsors could be asked to help entertain controversial American leader Mr Trump?

– The Queen

The Queen hosts the state banquet and will deliver a speech and propose a toast to Mr Trump as is the custom.

The monarch has already met Mr Trump – he joined her for tea at Windsor Castle last July.

As they inspected a Guard of Honour, Mr Trump walked along before standing still in front of the monarch, meaning she had to navigate her way around him so they could walk side by side.

He later said of the sovereign in an interview: “That is a beautiful woman.”

The Queen – the nation’s longest reigning head of state – is an expert at diplomacy, having entertained all manner of controversial leaders over the decades from Romania’s Nicolae Ceausescu to Russia’s Vladimir Putin.

– The Prince of Wales

While the prince has called climate change “the wolf at the door”, Mr Trump has called it a “Chinese hoax” and “bullshit”.

Charles, like the rest of the royals, did not meet Mr Trump during his visit to Windsor last year.

But Clarence House confirmed that the prince and the Duchess of Cornwall would be participating in the June state visit.

Charles and Mr Trump have encountered one another previously in New York during the prince’s 2005 tour to the US with Camilla.

The prince was also at former US President George HW Bush’s funeral in December, where Mr Trump was present.

Charles’s attendance – or rather his absence – at banquets has hit headlines in the past.

In 2005, when the Chinese president Hu Jintao made a state visit to the UK, the prince carefully side-stepped the issue, being out of the country on a tour of the US on the night of the official dinner.

He did not meet Mr Hu on the remaining two days of his visit.

The prince, a supporter of the Dalai Lama, had been accused of boycotting a Chinese state visit to the UK in 1999 by failing to attend the return banquet held for then-president Jiang Zemin.

Charles and Camilla often, but not always, take on the task of meeting and accompanying heads of state to the ceremonial welcome with the Queen, as they did with Barack Obama’s state visit in 2011.

They also sometimes host visiting heads of state for tea at Clarence House.

– The Duke and Duchess of Cambridge

William and Kate have attended a number of state banquets, including most recently one for the King and Queen of the Netherlands.

During Mr Obama’s 2011 visit, newlywed William and Kate did not attend the banquet, but had a special audience with the president and First Lady Michelle Obama in the afternoon.

The duke is unlikely to be impressed with Mr Trump’s previous comments about his mother.

Mr Trump once said he would have slept with Diana, Princess of Wales, without hesitation.

In a Howard Stern radio interview recorded just months after the princess died, he also branded her “beautiful” but “crazy”.

Mr Trump used to bombard Diana at Kensington Palace with massive bouquets, according to broadcaster Selina Scott, who said he saw the princess as “the ultimate trophy wife”.

She added that Mr Trump gave Diana the creeps: “It had begun to feel as if Trump was stalking her.”

Mr Trump also made remarks about Kate after she was photographed sunbathing topless by the paparazzi in France.

“Kate Middleton is great – but she shouldn’t be sunbathing in the nude – only herself to blame,” he wrote on Twitter.

 – The Duke and Duchess of Sussex

Meghan, who is counting down the days to the birth of her first child, will still be on maternity leave, having only just welcomed her new baby son or daughter a few weeks earlier.

Meghan was, before marrying into the royal family, a vocal critic of former reality star Mr Trump, backing his rival, Hillary Clinton, and suggesting before the 2016 election that she would leave the US if he won.

She previously labelled the billionaire “divisive” and a “misogynist”.

On a leaked tape from 2005 which surfaced during Mr Trump’s presidential campaign he was heard making lewd remarks about women.

“When you’re a star they let you do it. You can do anything,” Mr Trump said, adding later: “Grab them by the pussy. You can do anything.”

Harry has already met the First Lady, Melania Trump, while in Canada for the Invictus Games in 2017.

It could be this connection – and the fact that Harry has an American wife – which means the duke may be called upon to meet the Trumps during the high-profile state visit.

Harry, however, may still be spending time with Meghan and Baby Sussex as a new family of three.

According to Meghan’s father, Thomas Markle, Harry urged Mr Markle to give Mr Trump a chance.

The duke’s father-in-law shared details of their private conversation in an interview with ITV’s Good Morning Britain.

He said: “Our conversation was I was complaining about not liking Donald Trump, he said ‘Give Donald Trump a chance’.

“I sort of disagreed with that.”

– The Duke of York

Andrew, who often attends state banquets, shares a love of golf with the American leader.

Mr Trump is a huge fan of the sport and owns golf resorts in Scotland.

– The Princess Royal

Anne – known for her no-fuss approach – will be seen as taking no nonsense from Mr Trump if they are to meet.

The hard-working princess, who has devoted herself to public duty, has been described as aiming to serve, but not to please.
