Downton Abbey star Amy Nuttall ‘demands a divorce from cheating husband Andrew Buchan’

Amy Nuttall has reportedly demanded a divorce from her husband of 11 years Andrew Buchan, 44, just weeks after news of their split emerged.

The Downton Abbey star, 40, was recently spotted without her wedding ring, after her partner is said to have left the family home over Christmas to continue an affair with actress Leila Farzad, 40, who he met while working on the BBC series Better.

In a new development, it is now said that she’s keen to make the shocking split official by formerly ending their marriage and getting what she is ‘entitled’ to.

Andrew is best known for his role as Mark Latimer in popular series Broadchurch and married Amy in 2012, with the couple welcoming a son three years later, in 2015. The pair also have a daughter.

After being left devastated by her husband’s alleged infidelity, sources tell The Sun that Amy is now taking the power back after the betrayal, while also claiming that Andrew and Leila have already parted ways.

An insider told the publication that she has ‘decided to take back control’ by taking the lead in divorce proceedings.

While it is unkown whether Andrew and his alleged mistress are still involved, the source claims that the pair appear to have parted ways.

But confirming that this doesn’t change anything for Amy, the source said: ‘She’s told him she wants a divorce anyway. She’s been publicly humiliated and the pain has been unbearable.

‘She thought he was away working, when in fact he was often in hotels with Leila — once the truth emerged it was like being hit by a train.

They added: ‘Now she’s decided to take back control again and plan her own future. She’s going down the legal route and will get everything she’s entitled to.’

MailOnline has contacted representatives for Amy and Andrew for comment.

Actor Andrew is thought to have left the family home and moved in with Leila Farzad after meeting the her while working together on BBC series Better.

Leila married her husband James Maizels in 2013, and they have a daughter who was born in 2014. It is not known when they split.

The reports came just weeks after she shared a gushing Instagram post paying tribute to Buchan for ‘holding her up and wiping away her tears,’ alongside a snap of them filming the drama.

Andrew’s alleged affair with Leila was exposed after Amy discovered that he had purchased racy lingerie in a size that was not her own.

Friends claimed the actor informed Amy of his desire to terminate the marriage shortly before Christmas.

A source told The Sun: ‘The penny started to drop over a period of time. He was away a lot, which wasn’t unusual because of the nature of his work, but at one point Amy realised he had been staying in hotels very near to home — and wondered why.

‘As time moved on, there were some tell-tale signs that he had become close to Leila — just something in his mannerisms and in their social media posts together.

‘But the final straw was the lingerie — that’s what clinched it. Amy just knew instinctively that it wasn’t meant for her.’

Amy, who has been left so ‘crushed’ by the end of her marriage that she has been crying almost every day, struggled to raise a smile as she ran errands in Buckinghamshire.

The mother-of-two wrapped up against the cold in a padded navy jacket and swept her hair back in a chunky clip.

Speaking to MailOnline about the split, she fought back tears and confessed: ‘I can’t talk about it. I’m sorry, I can’t say anything.’
