Tony Blackburn has penned an emotional tribute to his sister Jackie, who has died after contracting Covid-19.
Broadcaster Tony shared the sad news on Twitter this morning, while explaining to loyal listeners that he would not be doing his usual Sunday show.
His BBC Radio 2 shows, meanwhile, had been pre-recorded after he learned of "lovely" Jackie's passing.
The 78-year-old has since been met with a flood of love and support.
Tony wrote: "I hope you enjoyed my @bbcradio2 shows this weekend which were recorded before I got the sad news that my lovely sister Jackie had passed away.
"She had been in hospital with Covid and had been home for a week but lost the battle. I love you Jackie R.I.P."

In a follow-up tweet, he thanked followers for their kind words, adding: "I need a bit of time to get over my sad news so won't be doing my Sunday Show this week, but will be back next week.
"Thanks for all the lovely messages my friends have sent me it's very kind of you."
His BBC colleague and news anchor Simon McCoy was among those to send their condolences, writing: "Thinking of you Tony..."


And actor Graham Cole OBE offered his sympathies, adding: "Sending all love and best wishes Tony & Debbie xx."
Jackie was Tony's youngest sister, and was born with infantile paralysis, meaning she had always been in a wheelchair.
Tony previously told The Guardian that he vowed to his parents to take good care of Jackie once they were gone.

"When my parents died, I asked Jackie to come and live with my wife, Debbie, and myself, but she chose to remain in Poole where she has lots of friends," he recalled.
"Jackie never complains. Her attitude to her life has altered my outlook on life. I have so much admiration for Jackie and I'm very close to her."
R.I.P. Jackie.
