Coronation Street 's Carla Connor and Peter Barlow have endured their fair share of ups and downs, but their relationship has appeared to be broken upon repair in recent scenes.

Thankfully, Coronation Street producer Iain McLeod has revealed Carla (Alison King) and Peter (Chris Gascoyne) will always love one another, despite the hardships their relationship may face.

Peter's battle with alcoholism is a huge storyline in the New Year, leaving him hospitalised, suffering from liver damage and mental health troubles.

Carla has desperately tried to help him, pleading with Peter to allow her to look after him.

However, Peter appears to have resigned himself to his impending death, telling his dad Ken Barlow (William Roache) he needs to accept he is dying.

With heartbreak ahead, McLeod has revealed Carla and Peter will face a tough few months, but their love is an enduring one.

Comparing them to legendary Hollywood couple Richard Burton and Elizabeth Taylor, he said: "They're Burton and Taylor aren't they, and I'm not the first person to say that.

"Indeed they've even described themselves as being the Burton and Taylor of Weatherfield onscreen.

Confirming their fate, McLeod added: "Yes, they will always remain in love."

McLeod said Carla and Peter "will always remain in love"

The 60th anniversary week last December saw Carla make a fatal mistake in sleeping with Adam Barlow (Sam Robertson), driving a wedge through her relationship with Peter.

Their plans to marry fell apart, and Peter ended up seeking solace in the bottom of a bottle, relapsing yet again.

While their romance is tested, McLeod has revealed Carla and Peter will come out stronger on the other side.

"I think the aftermath of what happened in the 60th will probably be the biggest test for Peter personally," he said.

"In terms of his mental wellbeing, his physical wellbeing, [he] is going to hit an all-time low, but in terms of his relationship with Carla, the intention of doing this story really was always to see them both make a terrible mistake."

He continued: "In Carla's case it was with Adam, in Peter's case it was hitting the bottle again, so they both made huge mistakes but actually they come out on the other side stronger than they ever have.

"So this is the sort of the last trial by fire of this relationship."

McLeod was full of praise for actors Alison and Chris, whose onscreen talent has won over the hearts' of viewers time and time again.

"They're both such incredible performers, I was watching some scenes the other day which are part of his story and they are so, so good and have such chemistry," he said.

"If you could bottle it and sell it I'd be a very wealthy man!"

Coronation Street airs on Mondays, Wednesdays and Fridays at 7.30pm and 8pm on ITV.
