Jamila

Nick Ashley-Cooper, the 12th Earl of Shaftesbury, wants his Tunisian stepmother, Jamila M'Barek, to lose her title, Countess of Shaftesbury.

"It's offensive that she has got that title, especially since she murdered the man she got it from, my father," he said.

The Earl spoke about his father's killing for the first time ahead of a More4 documentary looking at his attempt to rescue the Shaftesbury family name from bankruptcy and ruin.

The Aristocrats is a four-part series exploring modern day high society through historically prominent families.

It follows Nick Ashley-Cooper coming to terms with assuming the title of the 12th Earl of Shaftesbury in 2005, after his father's murder and his 28-year-old elder brother Anthony's sudden death from a heart attack weeks later.
