EastEnders has announced that the Baker clan is set to expand when Mitch's estranged brother and two nephews arrive in Albert Square this summer.
Mitch, played by Roger Griffiths, will have to deal with the return of his "charming older brother" Avery, played by Omar Lye-Fook.
"Almost always on the verge of causing trouble, Avery couldn't be more different to his little brother and his arrival will immediately cause heads to turn..." teased the BBC.
Joining Avery are his sons Felix and Finlay, played by Matthew Morrison and Ashley Byam, respectively.
"The youngest of the two brothers, larger-than-life Felix will throw himself into life in Albert Square, but with his quick-wit and frank honesty he'll be sure to stir up some drama along the way," said the BBC soap.
"Older half-brother Finlay has a different biological dad but was raised by Avery soon after birth.
"Finlay has sailed through life using his cheeky charm but is set to face a wake-up call as he begins life in Walford.
"Despite being the complete opposite of each other, Felix and Finlay present a united front and always have each other's backs."
"While Mitch dearly loves his nephews, it's fair to say he has a complicated relationship with his brother after not speaking to him for years and Avery's unexpected arrival is set to cause some issues for Mitch," the BBC added.
"Realising there must be a reason for Avery suddenly coming back into his life, Mitch is determined to get to the bottom of what's going on and find out what secret Avery is hiding..."
Chris Clenshaw, Executive Producer of EastEnders, said: "The Baker Family bring a fresh, fierce, fun and exciting energy to the Square.
"Felix and Finlay are two very different firecrackers and, yes, these brothers fall out, take the mick and challenge each other, but none of that compares to their unswerving love and loyalty they have for one another.
"They may be charming young men, full of sass, swagger and strength but these brothers are Bakers and, like their father, Avery, have their own unique way of surviving."
"The Baker family are just the start of some new faces landing in Walford later this year - so watch this space..." Clenshaw added.
The new cast members have already begun filming.
EastEnders airs on RTÉ One and BBC One on Mondays, Tuesdays, Thursdays and Fridays.
