In a plot twist airing later this summer, superbitch Janine Malloy (Charlie Brooks) is in for a surprise when Norman arrives as an unexpected guest for her grandmother's funeral.
Although Norman originally intends to leave after the service has taken place, he later decides to stick around in Walford as he is planning to contest his mother's will.
Shortly after Norman's arrival, sparks fly when he bumps into an old face from another lifetime - Pat Evans (Pam St. Clement).
Billed as "hapless, clumsy and unlucky in life", Norman is a lonely and good-hearted man who has a soft spot for Pat. However, whether he will finally get his girl remains to be seen.
Speaking of his EastEnders role, Layton commented: "I am thrilled to be joining such a wonderful cast and crew - Norman is a great part and I'm excited to play him.
"I can't wait to get stuck into life in Albert Square - and hopefully the odd tipple or three in the Queen Vic!"
Layton is best known for his role as junior doctor Paul Collier in Doctor at Large, Doctor in Charge and Doctor in the House, as well as appearances in Minder, BBC drama Sunburn and It Ain't Half Hot, Mum.
EastEnders viewers will see Lydia pass away in tomorrow night's episode of the soap, leaving Janine devastated and feeling more lonely than ever.
