The show also stars Sally Bretton as Lucy, Mack’s long-suffering landlady and object of his affection, and Katy Wix as their friend Daisy and Bobby Ball as Lee’s dad.
The new series sees the arrival of High Dennis and Abigail Cruttenden as Toby and Anna, a well-heeled couple who move into Lucy’s building and discover being neighbours with Lee is anything but straightforward.
Producers promise the show’s will-they-won’t-they tension will reach “unseen new highs” in an epic Christmas series finale that sees Lucy and Lee in previously uncharted emotional water.
Will they, or wont they… the time has come to finally find out…
Starts Friday 17th October on BBC One
