Nigel Havers and Rula Lenska are to return to "Coronation Street".
The 66-year-old actor will reprise his role as Lewis Archer and the 70-year-old star will return to the cobbles as Claudia Colby for separate storylines alongside Sue Nicholls" alter-ego Audrey Roberts.
A source said: "Producers are delighted to have Nigel and Rula back.
"They were both hugely popular on the show, and it feels like an age since either of them were last on the cobbles.
"They are returning this summer but at separate points and in different storylines.
"Both stories will involve Sue Nicholls, who plays Audrey."
Nigel was last seen in Weatherfield in February 2013 as former male escort Lewis when he fled to Belize after blackmailing Audrey's daughter Gail Platt (Helen Worth) for £40,000, while Rula hasn't been on the cobbles since May 2011.
The source added to The Sun newspaper: "Smooth-talking Lewis will have his eye on Audrey, while Claudia is a real thorn in her side, trying to poach her staff and stealing her customers.
"It will be lots of fun and much more like the Corrie comedy of old."
Lewis previously dated Audrey before stealing from Peter Barlow's (Chris Gascoyne) bookmakers and fleeing, but he later returned to pay up and make up with Audrey.
He went on to start dating Gail and pretended they would move to Italy together to start a new life.
In doing so, he persuaded her to take a £40,000 loan out against the house but stole the money after blackmailing Kylie Platt (Paula Lane) for Gail's bank account passwords.
He fled and left a DVD for the Platts to watch in which he slammed Gail and revealed what he had done.
But he sent £9,000 to Audrey and a bunch of flowers which read: "You were always the one. All my love, all my life, Lewis."
Nigel has previously said: "I would love to [return], actually.
"I do owe Gail 40 grand at the moment and I think as an honourable man, I'd like to pay that back. It was wonderful doing the show."
Claudia, who initially introduced Lewis to Audrey, enjoyed a love-hate relationship with her fellow hair salon owner during her time in Weatherfield, and she looks set to cause chaos upon her return.
