He added: “The Mitchells remain one of EastEnders’ defining dynasties, and we can’t wait to see them reunited again. As always when Grant is around, drama inevitably follows him…”.
Kemp plays one half of the soap’s iconic Mitchell brothers, alongside Steve McFadden in the role of Phil Mitchell.
Grant was last seen on screen in February 2025, when he briefly returned as part of the series’ 40th anniversary – following concerns about brother Phil’s mental health.
At the end of that spell, Grant left Walford for his home in Portugal, but is set to return again after being called upon by estranged son Mark.
In a statement, a spokesperson from the soap said: “This year, Grant is called upon by his estranged son Mark to return to Walford, marking the first time the pair will be reunited since Mark learned the truth about his true parentage.
“Grant’s arrival on Albert Square also comes amidst the deteriorating health of long time family friend Nigel. While full details of Grant’s comeback remain under wraps, viewers can expect explosive drama.”
Kemp said that “it’s especially an honour to be part of Nigel’s powerful ongoing dementia storyline”, which he says “holds deep personal meaning for me due to a close family connection in real life”.
Kemp rose to prominence playing Grant throughout the 1990s, before pursuing other acting roles and fronting a series of documentaries on gangs.
He returned to the soap for several episodes between 2005-2006, before again making a comeback in 2016 for a number of guest appearances.
