Shirley Bassey's homecoming concert in Cardiff next week could be her last in Wales, according to her sister.

"I think she wants to retire and you can see her slowing down and doing fewer concerts," said sister Eileen Hopkins.

"Every time she comes home, and now that she's getting older, she wants to feel more a part of the family and spend more time with her grandkids," Hopkins added.

Bassey will play to a sold out Cardiff International Arena on Tuesday.
