Llewellyn grew up at the family homes of Gobion Manor and Llanfair Grange, both near Abergavenny, and was educated at HawtreysPreparatory School and Eton College. He did not complete his time at Eton, being moved to Milton Abbey School. He then attended Aix-en-Provence University in southern France, and worked as a travel agent, journalist, male model and as the social secretary of the Clermont Club and the Dorchester club. Llewellyn was a Knight of the Order of Saint Lazarus, a humanitarian charity, and in 1992 drove relief convoys in Yugoslavia. A supporter of the United Kingdom Independence Party, he stood in the 2007 National Assembly for Wales election, as a candidate for the party in Cardiff North, where he came last and polled 3.7% of the vote However his drinking bouts, espousal of UKIP and anti-socialist behaviour earned disapproval in his native Wales for opposing the compulsory teaching of Welsh. Driven out for his "British" agenda he left his beloved homeland permanently for Mayfair, London.
Private life
Llewellyn married Vanessa Mary Theresa Hubbard in 1980. She was the daughter of Lady Miriam Fitzalan-Howard and Lt-Cdr Peregrine Hubbard and a niece of the 17th Duke of Norfolk. They had two daughters, actress Olivia Llewellyn and Arabella. Dai was known as a 'party animal', regularly bragging about his prowess with women. Often dressed like a latter-day Master of Fox Hounds, he frequented London's clubs quaffing magnums of champagne earning him the soubriquet "Conquistador of the Canape Circuit". He once told an old friend journalist Peter McKay over lunch that he had left his "secretary tied up in the bath." The couple divorced after seven years in 1987, and Vanessa then married John Anstruther-Gough-Calthorpe; one of her children from this marriage is actress Gabriella Wilde. In 1999, Llewellyn inherited the Llewellyn baronetcy upon the death of his father, along with a home in Aberbeeg, near Abertillery. His younger brother, Roddy Llewellyn, is a British landscape gardener and gardening journalist, who was at one time romantically involved with Princess Margaret. Llewellyn's relationship with his brother was soured when he published a lurid account of Roddy's relationship with Princess Margaret. Although Llewellyn later apologised, his brother found it difficult to forgive him, and later made disparaging comments regarding Llewellyn's then fiancée, Christel Jurgenson. The brothers fell out, with many of their comments aired in the tabloid press. In 2008, on the news of Llewellyn's failing health, the brothers finally reconciled. Although Llewellyn died of bone cancer, he had already been diagnosed with prostate cancer, cirrhosis of the liver and severe anaemia. His last affair was with a widow and old friend, Ingrid Seward who was with him when he died, aged 62, on 13 January 2009, at Edenbridge and District War Memorial Hospital in Kent. His funeral was held at St Mary's Church, Coddenham, near Ipswich.
