An interior designer who was cut out of her mother ’ s £2.5million will has won a legal fight with her brother to keep her home . Sunita Day , 45 , who once dated Sir Terence Conran , was disinherited by her gambling-addict mother Pamela Russell . But a judge ruled yesterday that she was entitled to keep an £800,000 flat she had been given in 1995 . Sunita Day , 45 , ( left ) was disinherited by her mother Pamela Russell before her death in 2013 and everything was left to her brother Rajan Russell ( right ) The court heard that restaurateur Mrs Russell , who died in 2013 , underwent a personality change after being diagnosed with cancer . She frittered away much of her fortune in casinos and turned against her daughter . Mrs Russell left her entire estate to Mrs Day ’ s older brother , investment banker Rajan Russell . He maintained the estate included his sister ’ s flat in Battersea , South West London . Mrs Day , who made headlines when she was in her 20s for ‘ stepping out ’ with designer Sir Terence , 38 years her senior , said the flat had been a gift to get her on the property ladder . Before her illness her mother , to whom she had been very close , often showered her with presents , she told Central London County Court . ‘ She was always buying me things like mink coats and jewellery – you name it I had it , ’ Mrs Day said . ‘ I was spoilt ... the flat just followed. ’ But she said her mother ’ s gambling addiction turned her into ‘ a harridan with a capital H ’ and at one point she feared Mrs Russell would have her ‘ bumped off ’ to get the flat back . Her mother had given her a luxury £800,000 flat in Battersea , south London ( pictured ) 20 years ago but Mr Russell claimed it was part of his mother 's estate . During her final years , her mother had visited casinos every night and even resorted to stealing gambling chips , Mrs Day claimed . She said she lived in fear of her multi-millionaire brother , whom she called ‘ bully boy Raj ’ , and that he was jealous of anything their mother gave her . Mr Russell , 47 , denied his sister ’ s claims . But after a four-day hearing , Judge Marc Dight ruled that Mrs Day was entitled to keep the flat , which had been ‘ freely gifted ’ . He rejected Mr Russell ’ s claim that she merely held the flat as a trustee and ruled he was entitled to only a £55,000 stake in the property to reflect a mortgage paid off by his mother . Judge Dight also ordered Mr Russell to pay most of his sister ’ s six-figure legal bill . However he rejected Mrs Day ’ s claims that she had been put under ‘ duress or undue influence ’ by her brother and mother . He said Mrs Russell ’ s personality had changed after her cancer diagnosis in March 2010 . In a document she wrote in May 2012 explaining why she had disinherited her daughter , she claimed Mrs Day ‘ never came to see me while I had breast cancer and has been very disagreeable all her life since the age of 14 . I feel like I have done three life sentences with Sunita ’ . The judge said : ‘ By the end of her life , and certainly from the time she was diagnosed with cancer , Mrs Russell had a deep-rooted and unhealthy gambling habit . ‘ She was very unwell . The evidence satisfies me that she was unkind to those around her , including Mrs Day . She was manipulative with her relatives and many of her friends. ’ Judge Dight said Mrs Russell had tried to pressure and manipulate her daughter into giving her back the flat but Mrs Day had a ‘ feisty ’ determination to hold on to the property . Mrs Day ( right , outside court this week ) 'stepped out ' with Sir Terence Conran ( left ) when she was in her 20s and previously gave an interview to a magazine which 'dealt ' with their relationship .
