According to the Daily Star, Peter will try to win back ex-wife Leanne, who will become engaged to her first husband Nick Tilsley once again later this month.

Peter will apparently say to Leanne in scenes to air next month: "You look like someone doing an impersonation of someone being happy.
"Marrying 'Bistro Boy' will be the worst mistake of your life," he will allegedly further warn, before claiming that they are both lonely without each other.
However, Leanne reportedly hits back, but will face a longer term dilemma over whether she can marry Nick and resist Peter.
Leanne reacts badly when her and Peter's divorce papers come through in upcoming episodes, suggesting she still holds a flame for the alcoholic bookies' owner.
Chris Gascoyne (Peter) and Alison King (Carla) returned to set in October following their respective four-month breaks from the ITV soap.
