Peggy, played by Barbara Windsor, has been one of EastEnders' most iconic characters and her death has left viewers heartbroken.
In the latest episode of the BBC One soap, Peggy was seen breaking the news to her son Grant - played by Ross Kemp - that her cancer had returned.
Later, Peggy, who took a series of pills throughout the episode, began hallucinating and 'had a conversation' with the ghost of her late-friend Pat Butcher, whose character was reprised by Pam St Clement for one final time.
Peggy told Pat's ghost: "I'm being eaten alive and it hurts and I can't wait.
"I don't want that to be me, I don't want to be that little old lady in the bed, with people saying, 'Remember her? Peggy Mitchell? She's all skin and bones'."
She then concluded: "I will go as I have lived: straight back, head high, like a queen."
Peggy then glammed herself up before taking more tablets, which took her own life. Notably, the EastEnders theme tune did not play as the credits rolled, before a final scene showed a clock stopping.
Following the emotional episode, fans took to Twitter to share their grief. TOWIE's Bobby Norris tweeted: "What an emotional but beautiful episode of #EastEnders.. #GoodbyePeggy #EELastOrders." Another viewer added: "Tonight's episode has broken my heart."
RIP Peggy, what a legend!
