Born Nina Kakkar in New Delhi, she is the daughter of an Indian diplomat. In 1996 she married Sir Charles Bracewell-Smith, the fourth baronet (of Keighley in the County of Yorkshire); he is the son of the former Arsenal director Sir George Bracewell-Smith, (second Baronet) who was on the Arsenal board of directors from May 1953 to September 1976. Sir George was in turn the son of the former Arsenal chairman Sir Bracewell Smith, who sat as chairman from 1948 to 1962.
Lady Bracewell-Smith was formerly a director of the Park Lane Sheraton Hotel. The Bracewell-Smith family have strong connections to hotels having previously owned the Ritz Hotel in London, which they sold in 1976, together with a large share of the Paris Ritz; they also held the majority of the shares in the Park Lane Hotel (built by Sir Bracewell Smith in 1920) until its £44m sale in 1996.
After World War II the majority of Arsenal shares, which in those days were not considered to be valuable and have never paid a dividend, were held by the Hill-Wood family and Sir Bracewell Smith, the M.P. for Holborn and a Lord Mayor of London, largely as a charitable exercise to provide recreational entertainment for the working people of North London.
The shareholding of Sir Bracewell Smith was divided between his son and daughter and ended up in the hands of his grandchildren, Sir Charles Bracewell-Smith, Clive Carr (Life-President), Richard Carr (still a director) and Sarah Carr, now Lady Phipps-Bagge.
Sir Charles Bracewell-Smith transferred ownership of his shares to his wife, Lady Bracewell-Smith, and she was made a non-executive director of Arsenal.
As of September 2007, Lady Bracewell-Smith owns a 15.9% stake in the club and is the third largest shareholder in the club following Danny Fiszman, with 24.11%, and Alisher Usmanov, who also owns more than 24% of the equity. Her appointment to the board in 2005 increased the members on Arsenal's Board of Directors to ten. She is one of only two female directors of a football club in the FA Premier League, and one of only four in the top two divisions, the other three being Brenda Spencer Wigan Athletic F.C., Karren Brady at Birmingham City and Delia Smith at Championship side Norwich City.
In April 2007 she joined with the other board members, her husband’s cousins, Danny Fiszman and the Chairman, Peter Hill-Wood, in resisting a take-over by Alisher Usmanov which was believed to have the support of David Dein.
She and her husband were ranked 751st in the Sunday Times Rich List 2008 with an estimated family fortune of £108m. She is also 44th on The Sunday Times UK Asian rich list,, 72nd on the women list and is in the European Rich List.
