Dame Barbara Windsor - best known for her roles as Peggy Mitchell in EastEnders and in the Carry On films - has died aged 83.
She died peacefully at 8.35pm on Thursday at a London care home with her husband Scott Mitchell by her side, after suffering from dementia.
Prime Minister Boris Johnson said Dame Barbara had "campaigned for the lonely and the vulnerable - and cheered the world up with her own British brand of harmless sauciness and innocent scandal".
In a moving tribute, Mr Mitchell called her his "precious Bar" and said: "I've lost my wife, my best friend and soulmate and my heart or life will never feel the same without you."
He said she had died from Alzheimer's and he had spent the last seven days by her side.
"It was not the ending that Barbara or anyone else living with this very cruel disease deserve," he said.
"I will always be immensely proud of Barbara's courage, dignity and generosity dealing with her own illness and still trying to help others by raising awareness for as long as she could."
Mr Mitchell said her final weeks were "typical of how she lived her life", being "full of humour, drama and a fighting spirit until the end".
The beloved soap and film star was diagnosed with Alzheimer's disease in 2014, going public with the news four years later.
Dame Barbara's on-screen children were among the first to pay tribute.
Steve McFadden, who plays Phil Mitchell in EastEnders, is said to be "devastated" by her death, according to a representative.
Danniella Westbrook, who played her on-screen daughter Sam Mitchell, tweeted: "MY HEART IS BROKEN. Bar you will always be in my heart forever. Good bye , I LOVE YOU XXX RIP Barbara WINDSOR."
Patsy Palmer, known for playing Bianca Jackson in the soap, shared photos of the pair together on her Instagram.
"I'm sitting here thinking of the hundreds of memories we shared," she said. "Too many to comprehend. We were like family for a long time - ups, downs, ins and outs but you will never meet a more professional actress than Babs."
She added: "I can hear that laugh now as I sit and think about her. I hope it'll ring in my ears forever."
Presenter Jonathan Ross wrote on Twitter: "Barbara Windsor in real life was everything you might have hoped for. So warm, so funny, so kind. Goodnight sweetheart x."
Comedian and actor Matt Lucas said: "You don't become a Dame by accident. Everyone knew Barbara Windsor and everyone loved her."
Lucas's Little Britain co-star, David Walliams, said: "Working with you, spending time with you, and being your friend was one of the greatest thrills of my life. You were the unofficial Queen of England, an icon for over half a century and treasured by the nation."
Known as The Queen Vic's feisty landlord, Windsor's character Peggy became an EastEnders stalwart and was famous for yelling "get outta my pub!" at rogue drinkers.
She made her debut on the soap in 1994 and quit in 2009, saying she wanted to spend more time with her husband.
Very sad. RIP.
Liked her in the Carry on films.
