The Cleaner cast: Meet the stars of Greg Davies's comedy

"When carrying out his duties, he stumbles across the strangest of people, from the victims' relatives, employers, neighbours and acquaintances to occasionally even the murderers themselves.

"And because he's a sociable type, he sometimes gossips more than he cleans…"

Across the six brand new episodes, Davies is joined by a raft of guest stars, some of whom you might recognise, others who you might not be familiar with.

Read on for a full rundown.

The Cleaner season 3 returning cast

The returning cast of The Cleaner includes:

• Greg Davies as Paul 'Wicky' Wickstead
• Zita Sattar as Ruth

Greg Davies plays Paul 'Wicky' Wickstead

Who is Wicky? Wicky is a state-certified cleaning technician with a very special field of work – he is a crime-scene cleaner responsible for the removal of any signs of death.

During the course of his work, he stumbles across a range of eccentric characters – from the victim’s relatives, employers, neighbours and acquaintances to occasionally even the murderers themselves, and is always quick to stop for a chat with whichever strange people he encounters.

What else has Greg Davies been in? Davies is best known for his comedy work – whether that be performing stand-up or presenting hit panel show Taskmaster. Previous roles include Mr Gilbert in The Inbetweeners and Ken Thompson in Cuckoo, while he also created and starred in the Channel 4 series Man Down.

Zita Sattar plays Ruth

Who is Ruth? A police officer. At the end of season 2, "Wicky" and Ruth share a kiss, but are they built for the long haul?

What else has Zita Sattar been in? You might recognise her from Casualty and children's show The Worst Witch.
