Two volunteers have been granted an audience with a member of the Royal Family.

Prestatyn sisters Andrea Williams and Kate Cooper, respectively treasurer and secretary of the Clwyd branch of the Motor Neurone Disease Association, were invited to a celebration at Aberystwyth University's arts centre with the patron of the charity, the Princess Royal.

The two former pupils of Prestatyn High School became involved with the charity after their father, Derek Vaughan Williams, was diagnosed with the condition in November 2013 at the age of 79. He died a year later.

Ann Williams, mother of Andrea and Kate, said: "Volunteering for the girls is a way of coping with their father's death. He would be very proud of them both."

The family have raised more than £15,000 since 2014 for MND through Derek's tribute fund and a variety of fundraising methods.

Andrea, 52, completed a 50-mile cycle and Neil Cooper, husband of 47-year-old Kate, ran a half-marathon in London last year. There have also been sponsored walks.

The Aberystwyth event welcomed committee members from all five branches of the charity in Wales to celebrate their commitment as well as meet Princess Anne.

Andrea said: "It was a lovely day. It was quite emotional at times when people were giving speeches about living with motor neurone disease.

"Princess Anne was lovely. She took the time to speak to everyone there and was very interested in what we had to say.

"I can't remember what I said to her! I was overawed and probably spoke gobbledygook!"
