When will Cassie leave?
In tonight’s episode of Coronation Street (Monday, March 2), Cassie attempted to propose to Steve McDonald ahead of her upcoming exit.

This parked Cassie’s plans for a moment, but will she and Steve get their happy ending before she leaves?

Cassie planned to proposed to Steve in Coronation Street
Cassie Plummer was fizzing with excitement, convinced this was finally the moment she would pop the big question to Steve. With wedding bells already chiming in her head, she roped in Tim and Mary as her co-conspirators. Tim distracted Steve with an oddly long stroll, while Mary proudly prepared a floral Street display spelling out a very bold ‘Marry me.’
But just as romance was about to bloom, fate barged in wearing steel-toed boots. Steve took a call and learned the devastating news that Jim had died. Panic followed. Tim ordered the flowers hidden, the proposal scrapped, and Cassie rushed in to offer emotional damage control.
Plans swiftly swapped sparkle for sadness as everyone gathered in the Rovers to raise a glass to Jim. Steve wrestled with his grief, clinging to a handful of rare, happier memories of his dad.
Meanwhile, Tracy clocked that Mary was acting even stranger than usual and soon spotted the engagement ring she had been guarding. Mary quickly urged Tracy to keep quiet, knowing Steve didn’t need any meddling on such a painful day.

Everything we know about Claire Sweeney’s exit as Cassie Plummer so far
Claire Sweeney is due to leave Coronation Street as Cassie Plummer this year, with the soap currently gearing up for an ‘explosive’ summer storyline.
While her actual exit storyline remains a secret for now, here’s everything we know so far.
Claire Sweeney plays Tyrone Dobbs’ mum Cassie Plummer on Coronation Street, having joined the cobbles in 2023 and quickly made her mark in Weatherfield. Now, after two years in the role, she’s preparing to step into a very different pair of shoes.
Cassie’s final scenes are expected to air in the summer, with a show spokesperson confirming to The Sun that Claire Sweeney remains on screen until then and will continue to make her presence very much felt. Details of Cassie’s exit stay tightly under wraps, but viewers are teased that the storyline builds toward a dramatic, ‘explosive’ farewell.
Off screen, Claire takes on a long-held ambition as she heads to the stage to play Miss Hannigan in Annie the Musical. While there are early hopes she might balance both Corrie and the theatre, the scale of the UK tour makes that impossible, prompting her decision to leave the soap. The tour kicks off in May 2026 and runs until March 2027, giving fans plenty of chances to see Claire shine once she waves goodbye to Weatherfield.
