Kat and Alfie are set to return to Albert Square

The couple were last seen on Christmas Day in 2005, when they left Walford for America.

Kat, played by Wallace, first appeared in the soap in 2000 and proved to be one of Albert Square's most popular characters.

Viewers were gripped by her romance with Alfie, as well as the storyline which saw her confess that she was Zoe Slater's mother rather than her sister.

She said of her return: "I've really enjoyed playing different roles over the last few years, but am excited to slip back into Kat Slater's stilettos. I've missed her."

Shane Richie said: "I'm very much looking forward to returning to EastEnders to find out what Alfie has been up to and what the future has in store for him. More than anything I'm looking forward to getting my face covered in Kat's lipstick again!"

Jessie Wallace is said to have signed an initial one-year deal to return to the soap.

John Yorke, controller of continuing drama, said: "Kat and Alfie are one of EastEnders' most loved and iconic couples so they're bound to get a very warm welcome from viewers when they return to Walford.

"We've had so many new and interesting characters settle into Albert Square since Kat and Alfie departed that it's going to make for fantastic viewing when the feisty, fun duo ride back into the East End."

EastEnders celebrates its 25th anniversary this year, and will broadcast its first ever live episode on February 19.
