Charles showed he's the King of cool this morning during a heatwave visit to a martial arts charity in London - where he met rap star Tinie Tempah. 

The Monarch donned a full suit, in light grey with a pale blue tie and matching pocketchief, despite soaring temperatures outside as he paid a visit to the Roger Gracie Brazilian Jiu Jitsu Academy in Hammersmith.

Charles was in West London to learn how the charity Reorg uses the martial art to support serving military personnel, veterans and emergency service workers facing mental and physical challenges. 

 One photo of the 77-year-old king saw him watching on - wearing a pair of plastic overshoes - as two fighters grappled with each other on a training mat.

Appearing on jovial form in spite of the hot weather London is enduring this week, the King spent time chatting to those helped by the charity. 

The Monarch spoke to Reorg's founder, Sam Sheriff MBE, a veteran of the Royal Marines - who also holds a black belt in the martial art.

Sheriff established the charity nine years ago and now has 200 partner academies, including The Roger Gracie Academy, which was founded in 2004 by its namesake, a ten-time world champion.

While Charles was presented with his own 'white belt', the first colour in the martial art's belt grading system, he also presented the most coveted colour to a member of the Reorg team. 

The Australian, also a trustee for the charity, has spent a decade reaching the highest colour after enduring a cancer battle.  

Charles also spent time with other students of the sport, including young people and those who enjoy over 50s classes. 

It's been a busy day for the monarch, who today also met with members of the Afghan Refugee Women's Cricket Team at Clarence House. 

The King listened intently as an Afghan Refugee Women's cricket team told him about their 'terrifying' 'escape' to safety following the return of the Taliban.

Charles heard about their ordeal at being smuggled out of Afghanistan when the the hardline regime resumed control of the country and issued the women with death threats - having banned woman from playing sport - and was given a beautifully-decorated bat as a gift.

Meeting the team at his London residence, the King said: 'So you had to escape as soon as you could, did you? In 2021?

'Was it difficult to get out of Afghanistan? Did you get out via Pakistan? And your families managed to come with you?'

Firooza Amiri, 21, told the King: 'It has been a very difficult and terrifying journey for all of us. There were a lot of Taliban check points. We thought it's going to be the last one, we won't survive any more. But we made it.'

The team, which is not recognised by their home country where all women's sport is banned, is in the UK for a series of matches.

Speaking to the group of 15 players, Charles said: 'I am so glad you can pursue what you really want to do.'

Charles asked: 'Did you manage to play cricket in Afghanistan before you left? You didn't get too many protests when you played, did you?'

The Afghanistan women's cricket team was formed in 2010 and played several international tournaments despite receiving Taliban threats.

When the regime took control of the country in 2021, a list of their names was circulated on a hit list, which included other female sports players. A female volleyball player for the country's national team was killed by the Taliban and the women were forced into hiding.

After being contacted by an Indian journalist, a group of Australian women devised a plan to evacuate the cricket team.

Melanie Jones, a former Australian cricketer turned commentator, joined forces with Emma Staples, now the Afghan team's manager, and Catherine Ordway, a sports lawyer.

By this stage, all flights out of the country were grounded.

Jones said: 'We ended up getting humanitarian visas with the Australian government and they then expired while some were still in the country. 

'We had the SAS from the Australian Army on the ground and they helped the players through about 8-11 checkpoints through Pakistan with their families. There were about 134 people we got out.

'They had a backpack each with their entire lives and had to burn anything that said they played cricket, all their cricket equipment.'

Most of the women now live in Australia, with one in Canada and one in the UK.

They will play the Cambridge University Cricket Club women's team on Saturday.

'My old university,' the King said.

While speaking to the women about how well they had learned different languages, one player asked the King to pronounce a 'posh' word for them.

Ekil Latifi, 21, who fled to the UK from Afghanistan at the age of 17, said: 'Your Majesty, would you give me a posh word, like 'lavatory'? Do you have one for me?'

Charles laughed and replied: 'I think I would need advance warning for that.'

Latifi, who came from the western city of Herat, was placed with a foster family after managing to take the last evacuation flight out of Afghanistan to Britain.

She has since worked as a coach at Lords cricket ground and said that the team's success had a significance for women left behind Taliban rule in Afghanistan.

She said: 'We're not just representing our team, it's about Afghanistan women back in our country and all the things that they can't do.'

Shabnam Ahsan, 18, from Kabul, said that it was 'so disappointing' that the team cannot compete in the T20 Women's World Cup hosted by England which coincides with their visit because they are not recognised by Afghanistan.

Ahsan added: 'When we found out we were meeting the King it meant a lot to us and it means a lot back in Afghanistan where women don't have the right to go out.

'We're here to fight for them.'

Hearing that the team now mostly lives and trains in Australia, the King said: 'You're getting all that high-powered Aussie coaching - no holds barred!'

Charles had planned to meet the team in the gardens at Clarence House but the event, which was organised through the UK foreign office, was moved inside due to the heat wave.

Walking outside for a photocall, the King was presented with a shirt signed by the players and a decorated cricket bat.

Accepting the gifts, the King laughed and said: 'I used to play cricket. Very badly!'

The white belt, bat and shirt isn't the only sporting garment the King has received this month, earlier in June, King Charles was presented with a personalised Grimsby Town FC jersey by the club's mascot during a visit to Blundell Park.

Charles met the Mighty Mariner during a tour of the club's home ground in Grimsby, Cleethorpes, as the monarch inspected the black t-shirt that read 'HM King Charles' with the number 3.

Last week, the King and Queen attended all five days of Ascot, leading the traditional royal procession down from Windsor Castle to the Berkshire racecourse in a fleet of carriages.
