THE glamorous Instagram page of a British fashion designer has ignited a feud with her aunts over the £5million proceeds from the family's Grade I-Listed farmhouse.

Jade Holland Cooper, 31, who owns the Holland Cooper luxury tweed brand, uses the site to post selfies posing with her expensive products, elegant race horses and her multi-millionaire husband Julian Dunkerton, 53 - who founded Superdry.

But one of her latest posts caused her aunt, Deidre Goddard, 72, to hit back over a disagreement with Jade's father, Oliver, 73, over the family inheritance, The Sunday Times reports

The irritated aunt and her sister Brigid Fairman, 66, have been rowing with their brother over the proceeds from their fathers estate.

Deidre left a nasty comment under a snap Jade posted of her appearance in the Sunday Times business section in May, saying: "Some of us know the truth about you, your family and money. Please don't take us all for fools."

Last year Rupert Cooper, Jade's grandfather, died and left the family manor Great Bricett Hall and its 415 acre farm to Oliver and also made him executor of his will.

The will also states that the two sister would receive an insurance policy worth £50,000 each while their younger brother John would get one worth £100,000, reported The Sunday Times.

In response to Deidre's comment Oliver wrote a furious letter to his sisters declaring his outrage that they had targeted his daughter when she had received nothing from the estate.

He also demanded that Deidre post a "detailed and unequivocal" apology to Jade on Instagram and post a hand-written letter to her Costwold home.

If his sister met his stipulations he would in return increase the amount handed to both of his sister to £100,000.

Deidre turned down the "bribe" and said she was angry at Jade for boasting about her wealth on Instagram at a time when Oliver claimed there was no cash to pay his father's bequests - at a time before the farm's sale.

Her sister said last week that the disparity in their father's bequests showed his "Victorian notion" of the role of women in the family.

Last week Oliver’s lawyer, Peter Crix from Gotelee solicitors, told The Sunday Times: “I am sorry if Mrs Goddard and Mrs Fairman are unhappy, but proper procedures are being followed.”

Jade had a lavish wedding in August which was attended by celebrities including Idris Elba and Craig David.

Later that same month her husband Julian, who is worth an estimated £441million, donated £1million to the campaign for a second Brexit referendum.

At the time she described her husband as an "amazing human being" and that she never thinks about their 22 year age gap.

Jade set up her clothing brand 10 years ago and now specialises in sexy tailored tweed jackets, luxurious fur trimmed capes and £599 leather trousers.

She said she got the idea for her business from seeing everyone where the same "bog-standard, green, itchy, masculine tweed" leaving a gap in the market for a more glamorous version.
