It has been confirmed to the BBC by Una Stubbs' agent that the actress passed away at her home in Edinburgh, surrounded by her family. Her agent confirmed that the actress had been ill for many months ahead of her death. 

The actress was best known by many younger fans for her starring role as Mrs. Hudson in Sherlock, the BBC's adaptation of Sherlock Holmes. The adaptation also starred Benedict Cumberbatch and Martin Freeman. During a woman&home exclusive Una Stubbs interview, she revealed her close friendship with Benedict saying that he always "goes to her for a hug!"

The veteran actress also had a long career as both a comedy and dramatic actress and had many highly acclaimed roles throughout her long career.

Una first came into the public eye when she starred in Cliff Richard's 1963 film, Summer Holiday as Sandy. She later appeared in Cliff's 1964 film, Wonderful Life, as the character Barbara.

Una was also very well known for her role in Till Death Us Do Part, a BBC sitcom that ran from 1965 to 1975.

Una played the role of Rita Rawlins, and also starred in the first two series of the show's sequel, In Sickness and in Health. She reprised her role as Rita and the show ran from 1985 and until 1992.

The actress was also well known for her role as Aunt Sally in Worzel Gummidge. The late actress starred in 21 episodes of the show between 1979 and 1981. 

The star will also be fondly remembered as Miss Bat from The Worst Witch, a character in the children's series that she starred in from 1998 until 2000.

Una made guest appearances on various shows like EastEnders, Midsomer Murders, Benidorm, The Catherine Tate Show, and Heartbeat.

Many fans of the actress and fellow actors have taken to social media to share their memories of Una and also share their sympathies with her family.

"Devastated to hear about the passing of the brilliant Una Stubbs. My thoughts go out to her family & friends at this very sad time," said Joanna Lumley on Twitter.

Louise Brealey, who played Molly Hooper in BBC's Sherlock shared her condolences on Twitter. 

"Too upset to write. Can’t find any words worthy of you just yet. Thinking of your sons, who you loved with all your mighty heart." 

She later added, "Love you, Una," and shared a photograph of the late actress with a big grin. 

Another fan and Twitter user shared a cherished memory that she shared with the late actress.

"I was (only just) 18 when I worked as an extra on Sherlock. It was my first ever job and walking onto the set for the first time was so nerve-wracking. Una Stubbs was lovely. She had a smile and a kind word for everybody, cast, crew and extras alike. Thinking of her family," said the fan.

One of Una's son's Christian Henson, said, "Some of you may have known her as Rita, as Sally as Bat or Hudson but to my two brothers and I she was known as Mum. Thanks for everything Mum RIP."

Rebecca Blond, Una's agent who she worked with for more than 20 years also spoke about the star's passing.

"We are desperately sad to have lost not only a wonderful actress, whose screen and stage career, spanning over 50 years, was so extraordinarily varied, from Till Death Us Do Part to Sherlock, as well as memorable performances in the West End, at the Old Vic, Donmar Warehouse, Sheffield Crucible and National Theatre, but also a wickedly funny, elegant, stylish, graceful, gracious and kind and constant friend."

"She was also a highly respected and exhibited artist. We will miss her enormously and remember her always.”

Rest in peace, Una.
