CORONATION Street legend Debbie Webster is going to suffer a shock collapse this week.

The businesswoman – who is played by actress Sue Devaney in the ITV soap – has been hiding her serious health issues for quite some time.

Viewers known Debbie was diagnosed with young onset dementia earlier this year much to her devastation.

Now this week things will get on top of her as she struggles with the aftermath of breaking up with Ronnie Bailey to spare him from watching her decline.

When Debbie admits to Bernie that she finds it hard being in the same room as Ronnie, Bernie suggests they head to her hotel and have a few drinks there instead.

Debbie and Bernie arrive in the Chariot Square bar to find Brody there enjoying a drink with a mate but when the troublesome teen fails to provide ID, Debbie loses her temper and, picking up his drink, smashes it on the bar.

Later in the week Bernie worries for Debbie as she forgot to pay in the cafe.

Meanwhile Debbie breaks the news to Ronnie and Leanne that she needs to cancel the awards ceremony as there’s a flood at the hotel, but Leanne offers to host it at Speed Daal.

As Ronnie and Leanne share a laugh, Debbie watches.

Later Debbie makes a disturbing discovery, when she sees Carl telling Abi that they’re meant to be together.

With horror they realise Debbie is watching them – but what happens next is a shocker.

Suddenly Debbie collapses and as she regains consciousness, Kevin and Abi tell her she’s going to hospital.

But Debbie reveals that she already knows what’s wrong and she’s got dementia.

How will her family react and will Carl and Abi use her illness to hide their affair?
