WATCH: 'Get outta mah pub!' - Peggy Mitchell's top 6 Eastenders moments
Peggy Mitchell has been involved in some of EastEnders' most popular storylines over her reign in Albert Square.
She has beaten breast cancer twice, been engaged or married to almost every eligible man of a certain age and slapped everyone who crossed her.
But as she loses her battle with terminal cancer, here are some of her most memorable moments.
When Dame Barbara Windsor made her first appearance as Peggy
During her first episode, Peggy visited son Phil in hospital. "Can't take my eyes off you, can I? Not for two minutes," she said. She immediately made the role her own, banishing memories of the first person to play Peggy.
When she found Frank's leaving letter and read it out to the entire pub
In 2000 Peggy found out her husband Frank Butcher was having an affair with his ex-wife Pat and was planning to run away with her. Peggy found out and humiliated the couple in front of everyone in the Queen Vic by reading Frank's letter aloud. "One thing I've learned since I've been married to Mr Butcher is never underestimate his capacity to make a cock-up of things!" she cried before slapping both Frank and Pat.
When Peggy learned she had breast cancer
It was a storyline handled with sensitivity and acted with aplomb in 1996. The cancer returned in 1999 and Peggy made the decision to have a mastectomy. Hundreds of viewers wrote to the BBC praising Dame Barbara and EastEnders for the way the difficult subject was tackled.
When Frank's former wives came to blows after learning of his death.
"Get outta mah pub!" Peggy screamed at Pat as they rowed over which of them he had loved more. "You bitch!" cried Peggy as she slapped Pat. "You cow!" Pat responded, slapping her in return.
When Boris Johnson, then Mayor of London, visited Walford and had a run-in with the fiery landlady
"I do so admire a man who devotes his life to serving society. I nearly went into politics myself you know," Peggy told him.
When she got told to "get outta my pub."
Peggy's own catchphrase was used against her when she reappeared at the Old Vic and made remarks about the cleanliness of the establishment. Not taking too kindly to it, new landlord Mick Carter gave Peggy her marching orders.
Peggy's final appearance in EastEnders will be broadcast at 7.25pm on BBC One.
