A statement from her agent said: "It is with great sadness that we announce that English singer-songwriter Judy Dyble passed away on July 12 following a long illness borne with great courage.

"We wish to express our deepest sympathies to Judy's family, friends and many associates from her musical career at this time."
Her family "would like to thank her fans for their messages and good wishes on social media over the last few weeks", it said.
David Longdon, who had been recording music with Dyble which is set to be released in the autumn, also paid tribute to her.
He said: "It is with great sadness that I write to say that my dear friend Judy Dyble passed away this morning."
