Bonnie Langford is to joins the cast of EastEnders.

The star, who first rose to fame as a child in the 1970s, is joining the soap as Carmel Kazemi, the mother of Kush one of the soap's new regular characters, the BBC announced today.

Her character is described an Essex girl at heart, and an overly protective mother who loves her children - but has a tendency to embarrass them.

Best known for her stage roles in Chicago and Cats, as well as playing Doctor Who's assistant in the 1980s, Langford said: "I'm so thrilled and delighted to be part of EastEnders.

"I'm a great fan of the show and think the recent 30th anniversary was sensational and shows just how good British television can be. To be part of this family is an absolute privilege."

Talking about her arrival, executive producer Dominic Treadwell-Collins said: "Bonnie Langford is a British institution - and an old-school hard-graft actress gifted at both comedy and serious drama.

"Bonnie brings wit, pathos and a touch of class to Carmel Kazemi - a thoroughly modern Essex divorcee who isn't quite ready to cut the apron strings firmly attached to her son Kush. Even if it means clashing spectacularly with an already prickly Shabnam (Kush's girlfriend)."

She will start filming her scenes this month and will make her first appearance on screen in June.
