Cheat Sarah Platt terrified as Adam Barlow makes a shocking discovery in Coronation Street

ADAM Barlow is due to celebrate his birthday during an upcoming trip to the cobbles.

But the celebrations go south when the solicitor makes a shock discovery about his wife Sarah next week in Coronation Street.

The solicitor portrayed by Sam Robertson has tried to keep things afloat at his law firm by helping Damon Hay (Ciarán Griffiths).

Little does he know that the thug had a fling with his wife, Sarah Platt (Tina O’Brien).

The Underworld PA has been trying to keep her attraction to Damon under wraps but secrets rarely ever stay hidden in the cobbles.

Coming up on ITV next week, Adam books a table at the Bistro for his birthday as Damon offers to throw in a bottle of champagne – will Sarah be able to mask her unease?

While this remains to be seen, Sarah later takes Adam out for his birthday lunch at the Bistro, where he tells restaurateur Nick Tilsley (Ben Price) that there may be a problem with the late licence.

Adam explains some locals have raised objections against the late licence, which would allow the Bistro to host events they need to keep their business intact.

Regular viewers of the Manchester-based drama will remember Damon suggested the Bistro turns into a nightclub to attract a younger clientele.

Soon enough, Damon makes things uncomfortable for Sarah.

The criminal joins Adam and Sarah at their table, leaving her squirming.

Matters go from bad to worse when local politician Maria Connor (Samia Longchambon) lets slip that Sarah was one of the residents who raised objections about the late licence.

Nick and Adam are both furious with Sarah, unaware she went against the late licence to get away from Damon who, watching her stand in the firing line, enjoys her discomfort.

In later scenes, Sarah speaks her mind to Nick and Leanne Battersby (Jane Danson) telling them that their late licence idea is a terrible one.

Nick later calls at the Rovers and tells the locals there will be a meeting at 2pm on that same day to air all opinions on the late licence.

But when one Weatherfield resident asserts they have no objection to it, Nick is baffled and Sarah’s lies could unravel.

As the meeting to discuss the late licence is about to start, Damon vanishes, leaving Nick and Leanne wondering where he got to.

Could his fling with Sarah come out in the open?

Coronation Street airs every Monday, Wednesday and Friday from 8pm on ITV.
