Coronation Street's Sarah Barlow has a big decision to make tonight (February 13) as her nemesis Carla decides to give her a lifeline.

Sarah was recently caught out for betraying Carla after using her factory and resources to set up a rival business.

This came just weeks after Sarah had walked out of her job at Underworld after tensions with her no-nonsense boss.

Sarah has been working on her plans with help from business partner Michael Bailey and her uncle Stephen Reid.

What to Read Next

Last week, Carla seized their designs after realising that Sarah and Michael had worked on them at the factory – and during work hours when they were previously employed there.

Under the terms of their previous contracts, this gave Carla ownership of the designs.

In Monday's episode, Carla tries a peace-making approach after her triumph over the plotters.

Carla tells Sarah that she can finish working on her designs and get involved in the planned deal with businessman Rufus again.

However, Carla also insists on an apology – meaning that Sarah will have to swallow her pride if she wants things to get back to normal.

Is Sarah prepared to make peace with Carla? And how will Michael feel about the second chance?

Corrie bosses have named Carla as one to watch this month, as her feud with Stephen takes a sinister turn in upcoming episodes.

Wanting to undermine Carla's position at the factory, Stephen starts spiking her drinks with LSD. As the side effects take hold, Carla's husband Peter fears that her psychosis has returned.

Todd Boyce, who plays Stephen, recently said: "[Carla] is a very popular character. Up until now [Stephen] has targeted people who are relatively new characters that people haven't really got to know but this is different.

"Chris Gascoyne [who plays Carla's husband Peter] has been so lovely about it, he said, 'Oh mate you have no idea what you are in for when this starts'.

"Ali [King] and I have had some great scenes together, really fiery scenes and I have enjoyed that and I think people have enjoyed her getting one over on him, so they will hate it when the tables are turned."

Coronation Street airs on Mondays, Wednesdays and Fridays at 8pm on ITV1 and streams on ITVX.
