[6] David Sterne made a guest appearance as Aunt Sal's bereaved husband, Harold Martin.
[7] In February 1996, it was announced that comedy actress Anna Karen would be joining the cast of EastEnders as Peggy Mitchell's sister Sal.
They reportedly failed to lure back June Brown, who played Dot Cotton between 1985 and 1993 (although they were successful in doing so a year later).
[10] Commenting on her casting, Karen said, "It's great to be back on the box and a real treat to be working alongside my old mate [Barbara Windsor].
Sal is a heavy smoker and when visiting her sister, enjoys parking herself at the end of the bar with her cigarette (that is, until the smoking ban, when she would just go upstairs).
She is married to downtrodden Harold, and mentions a son in January 1997 and a daughter to Peggy at Grant (Ross Kemp) and Tiffany Mitchell's (Martine McCutcheon) wedding blessing ceremony.
On 8 July 2008 she returns again to keep an eye on Billy (Perry Fenwick) and Honey Mitchell (Emma Barton) whilst they look after The Queen Vic as Peggy is away.
She spends Christmas Eve 2008 with Peggy, complaining about the price of her taxi and joking about Jean Slater's (Gillian Wright) health condition.
Peggy returns home the following week but after feeling let down by Phil who won't kill Archie, she goes away on holiday with Sal to the Bahamas.
Sal returns again in November 2013, when she turns up uninvited for Roxy's hen party, before her wedding to Alfie Moon (Shane Ritchie).
Sal rudely expresses her doubts about Alfie and marriage in general, stating that women in the Mitchell family are cursed when it comes to love.
She speaks to Ronnie, off-screen and Peggy reveals that she does not want Phil to marry Sharon Rickman (Letitia Dean).
She ultimately fails in the task, but reveals Peggy's feelings at the reception to all the guests by reading a text from her sister.
She returns in November 2015 for a family meal where Ronnie is arrested for murder, and she along with the other Mitchells disown Roxy after she is uncovered as the person who called the police.
In January 2016, Phil contacts Sal, asking for Louise's (now played by Tilly Keeper) address (albeit off-screen).
Sal later returns in December 2016 for Ronnie's hen party for her second wedding to Jack, where she reveals she has taught herself how to read tarot cards.
