The star, who also appeared in films such as A Clockwork Orange and Room At The Top, died in a London hospital after a battle with cancer.
She was best known to TV viewers for her role as shop steward Paddy in The Rag Trade, who punctuated the show with her call to action: “Everybody out”.
Among those today paying tribute to Mim – as she was known to friends – were Lord and Baroness Kinnock.
In a statement they said: “As an actor Miriam Karlin was superbly talented in roles of every kind. As an activist for freedom she was supremely brave and persistent.
“Mim was easy to love, an infectious friend, a true comrade and a sparkling spirit. She will be mourned by all who work for justice, admire creativity and enjoy fun.”
The Hampstead-born Jewish actress – who lost some of her family in Auschwitz – trained at RADA, and cut her teeth as a performer with forces entertainment organisation ENSA.
She performed in rep, making her film debut in 1952 in Down Among The Z Men.
Later roles included appearing opposite Lord Olivier in The Entertainer, and she was the “Cat lady” in an infamously brutal scene in which she was beaten to death in A Clockwork Orange.
Her trade union and welfare work was recognised with an OBE.
