Tune in to ITV on Monday 4th January at 9pm, for a unique documentary, When Ant and Dec Met The Prince: 40 Years of The Prince’s Trust.

Viewers will see HRH The Prince of Wales talking about the upcoming 40th anniversary of The Prince’s Trust, his life as a grandfather and amusing anecdotes from his days in the Royal Navy.

The 90-minute special, which was filmed over a year, sees Ant and Dec granted a real insight into the work of The Prince’s Trust as they accompany HRH on a number of engagements – chatting to him along the way, meeting people who have benefited directly from its work and witnessing, first-hand, the passion that The Prince has for The Trust he founded in 1976.

With extensive access to Clarence House, St James’s Palace and Kensington Palace, Ant and Dec talk openly to those closest to His Royal Highness – The Duchess of Cornwall, The Duke of Cambridge and Prince Harry – who reveal what drives HRH in his work for charity and also share some revealing and funny stories from their lives with The Prince.

On setting up The Prince's Trust, HRH says:

Just getting The Trust off the ground was quite difficult; we had to overcome all these people who didn't see the point.

Talking about the evolution of The Prince's Trust, HRH adds:

“You have to keep ahead of the game all the time, you can’t just sit back and say, ‘Done a marvellous job,’ because that’s how all sorts of organisations fold, because you become absolutely static, when in fact you need to be constantly thinking and aware of issues that are arising to try and make sure you are relevant.”

Ant and Dec, long-term ambassadors for The Prince’s Trust, join HRH on a visit to HM Prison Parc to see with their own eyes the work the charity does there with the young offenders. The duo also visit Dumfries House in Scotland, where Prince’s Trust trainees help serve dinner, and the pair get invited to spend the night there with their wives, having sampled a taste of  Royal hospitality. They also go aboard HMS Belfast, where they meet some of The Prince’s former shipmates from his naval days, when he was inspired to set up The Prince’s Trust.

As they reflect on their own 40 years, Ant and Dec head back to their home town of Newcastle and meet up with fellow Geordie Cheryl Fernandez-Versini, who takes them around her childhood haunts and shares her experiences as an ambassador for The Prince’s Trust.

Talking about The Prince of Wales, Ant says:

You can’t deny that the work he’s done with The Prince’s Trust…it just works, he’s helped people, he continues to help people and good for him.

Dec adds: "There are those that will say he was born into this position of privilege and he can’t possibly empathise with the normal man on the street and the issues that face the ordinary man, but I think he can."
