Mo Butcher is a fictional character from the BBC soap opera EastEnders, played by Edna Doré between 1988 and 1990.

She disapproves of the way Frank is raising his teenage children Ricky (Sid Owen) and Diane (Sophie Lawrence) and immediately clashes with his fiancée Pat Wicks (Pam St Clement), bringing up her past reputation as a prostitute and threatening to put a halt to their impending marriage.

During her time in Walford Mo has an array of jobs; she first works in the kitchens of The Queen Victoria, then on Arthur Fowler's (Bill Treacher) fruit and veg stall and then in Ali Osman's (Nejdet Salih) café.

Fiercely loyal to her family, Mo sticks by her son through his financial woes and tries her best to help him out by offering Frank her late husband Chike's life insurance money.

Despite being protective and doting on her family, Mo is not blinkered to their faults, even in a rare moment supporting Pat in her decision to put Janine in therapy when her behaviour becomes out of control.

Mo eventually warms to Pat, seeing that Frank does love her, and arranges for them to be married in great East End style, complete with a horse and carriage, Pearly Kings, a street party and jellied eels.

Her busybody attitude results in few friendships in Walford for Mo, but she becomes close to Marge Green (Pat Coombs), despite belittling her.

[1] Since the show's inception in 1985 and up until 1988, one of the soap's main focal points, The Queen Victoria (The Vic) public house, had been inhabited by the Watts family; however, actors Leslie Grantham and Anita Dobson who played landlords Den and Angie Watts resigned in 1988, meaning the soap's bosses had to find a new family to inhabit the Vic.

[2] Kingsley described Mo as a woman who sought status, suggesting that she wished to be "Queen Bee" when she moved to Walford and regarded Frank's new wife Pat as "nothing more than a pushy interloper".

[2] Initial storylines centred upon clashes between Pat and Mo, with Frank trying to find a compromise between the bickering women in his life.

"[4] Edna Doré's portrayal of Mo's descent into Alzheimer's has been described as "deeply moving" by John Millar of the Daily Record.

[5] Former executive producer of EastEnders, Michael Ferguson, has suggested that Mo having Alzheimer's in 1990 gave people permission to talk about an illness "that had been almost too distressing to discuss in public before.
