Actor Ross Kemp is to reprise his role as EastEnders hardman Grant Mitchell, in a "brief return" to say goodbye to on-screen mother Peggy.
Kemp, who last appeared regularly in the soap in 1999, will be reuniting with the Mitchells as Dame Barbara Windsor's character passes away from cancer.
Peggy Mitchell made a surprise return to the soap last week to inform her other son Phil - played by Steve McFadden - that her cancer had returned.
She is not scheduled to appear again until her final episodes in late spring, when Kemp will also return.
Ross Kemp said the offer of returning for Peggy's final episodes was "something I could not turn down".
His return could cause some drama in Albert Square, which plays host to Grant's ex-wife Sharon (Letitia Dean) who is currently married to his brother Phil, and Phil's ex-wife Kathy (Gillian Taylforth) who had an affair with Grant.
