Coronation Street fans have been on tenterhooks waiting to find out who'll be playing Ken Barlow's son Daniel and grandson Adam - and the news is finally in. Adam Barlow is the son of Mike Baldwin and Ken's late daughter Susan. He's been off living in Canada since he left all the way back in 2007. He'll be played by Sam Robertson, who previously played Adam from 2004 to 2007. Iain De Caestecker was the first to play the part from 2001 to 2003. Sam said: "I'm delighted to be back, Coronation Street was my first job as an actor and is a special place for me. "As a young actor it was a little overwhelming so I'm looking forward to coming back and stamping my mark on the character, I feel there's unfinished business with Adam." Rob Mallard will play Daniel, Ken's son by Denise Osbourne - a character viewers last saw nearly a decade ago. He was previously played by Lewis Harney and Dominic Holmes. Rob said: "It feels great to be starting work on Coronation Street and I'm looking forward to getting to know everyone. "I grew up watching Coronation Street, so the chance to be in it, especially playing a part like Daniel, is very exciting." Producer Kate Oates said: "The Barlows have been at the centre of Coronation Street since it started in 1960 and I felt it was time to remind ourselves of the dynasty that Ken has built up over the past 50 years. "I am excited about the dynamics of having the different generations living together and exploring the drama that will bring." Producers had also announced that Peter Barlow (Chris Gascoyne) would be returning to Weatherfield. Kate added: "Peter turns up first in October and almost immediately his arrival has consequences for the family. He is followed in early November by Adam and Daniel. "I am delighted to have Sam back, his time away from Weatherfield has hardened Adam and although he is a Barlow the Baldwin genes are evident from the moment he arrives." She continued: "Daniel is a different Barlow altogether, more sensitive and bookish, he is clearly a chip off the old block, but there is more to Ken's youngest son than meets the eye. Rob is a talented young actor who is perfect for the role."
