Here's some of the etiquette Donald Trump will have to try to stick to on his visit to the UK

After months of debate, protests and to’ing and fro’ing, Donald Trump is visiting the UK.

The US President is in the UK with wife Melania and has already sparked controversy by an interview in The Sun in which he disagreed with Mrs May’s stance on Brexit, said Boris Johnson would be a great Prime Minister, and blamed Sadiq Khan for terrorism.

Mr Trump travelled to Chequers for talks with Mrs May after a dinner at Blenheim Palace on Thursday night, and was set to have afternoon tea at Windsor Castle with the Queen. He is also due to travel Scotland to play golf on one of his courses.

The trip may not technically be a full-blown state visit, but there is still certain etiquette the famously unorthodox President have to abide by.

Here are some things he should probably stick to – though who knows if he will…..

When he meets the Queen…

There are a whole load of do’s and don’ts when it comes to meeting royalty – especially the Queen.

They include making sure you’re early – not something Mr Trump has the best track record with. He hit the headlines when he was late for the G7 gender equality breakfast in June and more recently he was late to the opening of a campaign rally for South Carolina’s governor.

It’s against royal etiquette to touch the Queen – though you can shake her hand if she offers it.

But Trump wouldn’t be the first to break it if he does slip up – in 2009 Michelle Obama touched the Queen when she met her.

It’s customary to bow or curtsey when you meet the Queen, which could cause a few problems for the US President.

Back in 2012, Mr Trump criticised Barack Obama for bowing to foreign leaders, calling him “an amateur”.

But he then went on to appear to almost curtsey, and to bow his head, while receiving the Collar of King Abdulaziz al-Saud – Saudi Arabia’s highest civilian honour – from the country’s king last year.

It’s also advised that you don’t speak unless spoken to – something Mr Trump might struggle with, given he rarely keeps his thoughts to himself.

Etiquette also dictates that you use the right greeting when being presented to the Queen – the correct address is Your Majesty and subsequently Ma’am, pronounced like jam.

However, given that Mr Trump has appeared to get his own wife Melania’s name wrong in the past, this could well prove difficult.

When he meets the Prime Minister…

Much was made of Mr Trump holding Theresa May’s hand during her visit to the White House in September 2017.

Mrs May later suggested it was a simple “moment of assistance” but the picture made headlines around the world, with some people suggesting it symbolised the leaders’ closeness.

Either way, they might not want to hold each other’s hands this time round.

When it rains

Hogging the brolly is a big no-no when it rains, but Trump has got form.

In January, he was accused of being ‘ungentlemanly’ when he kept his umbrella to himself as he boarded Air Force One in Florida in the rain.

While the President protected his hair, wife Melania and son Barron were left out in the cold as he refused to shared the brolly.

When you play golf

According to the a post on the PGA website, there are a few pet peeves when it comes to golf.

They include lying about your handicap, with ‘bad scorekeepers’ said to be some of the most annoying people on the green.

Others are those who talk on their mobile phones or so-called ‘club throwers’ – presumably the ones who don’t take losing too well.

Another irksome character is the ‘Member who acts like he owns the course’ guy, says the post, which given Mr Trump actually does own the course, could be interesting…

In general

On top of specific situations, there is a whole load of general etiquette Donald Trump should probably try to stick to – but might struggle.

According to etiquette bible Debrett’s, when making polite conversation you should: “steer clear of religion and politics and don’t talk shop to people other than colleagues”.

It adds: “It is unwise to make assumptions, for example that everyone may have the same background or views as yourself.”

It says you should probably wait until you know someone better before braving difficult topics – but Mr Trump has never been a stranger to a bit of controversy, so is unlikely to tread carefully when it comes to the subject matter of conversations.

According to Debrett’s, if you make a blunder you should apologise “as quickly and sincerely as possible” – but apologising isn’t something that seems to come easily to Mr Trump.

It took a grilling from Piers Morgan to get the US President to finally agree to apologise for retweeting Far Right tweets, and there are several other occasions where he’s refused to back down.

The American leader didn’t apologise after apparently referring to Haiti and African countries as “s***hole countries” and has never issued a full apology for comments made in an audio recording in which he said he had the right to do “whatever he wanted” with women, as he was a ‘star’.
