Harding’s mother Marie shared the heartbreaking news on Sunday, saying: “It’s with deep heartbreak that today I’m sharing the news that my beautiful daughter Sarah has sadly passed away.
“Many of you will know of Sarah’s battle with cancer and that she fought so strongly from her diagnosis until her last day. She slipped away peacefully this morning.
“I’d like to thank everyone for their kind support over the past year. It meant the world to Sarah and it gave her great strength and comfort to know she was loved. I know she won’t want to be remembered for her fight against this terrible disease – she was a bright shining star and I hope that’s how she can be remembered instead.”

“A part of me or us isn’t here anymore and it’s unthinkable and painful and utterly cruel. She would have loved your messages today.”
Roberts described her bandmate as “Electric girl” and added: “You gave it everything and still with a smile. A white butterfly flew past my window this morning before I knew, it must have been you.”
