Her return is a key signing for new show boss Kate Oates.

EastEnders viewers will see Bianca, who made her debut 25 years ago, reunited with troubled daughter Tiffany, played by Maisie Smith.

A soap insider said: “Bosses are delighted to be getting Patsy back. She’s a real Enders icon and fans love seeing old faces return.

“She has yet to get her scripts but she will no doubt be at the centre of drama when she returns in the autumn.

“She starts filming in the next few weeks and can’t wait to get going again.”

Patsy joined EastEnders in 1993, left in 1999, and returned for a second stint in 2008 before quitting again in 2014.

Bianca’s wedding to Ricky Butcher, played by Sid Owen, in 1997 drew one of the biggest soap audiences ever — more than 22million.
