James Spencer-Churchill, 12th Duke of Marlborough

Born in Oxford,[1] he was educated at Harrow School[2] and the Royal Agricultural College.[3] In a bid to safeguard the Blenheim Palace estate from the then Marquess's excessive behaviour, his father won a court battle in 1994 to ensure he never won control of the family seat, but their relationship may have improved later.[4]

In 1995, he spent a month in prison for forging prescriptions.[5] In September 2007, he was sentenced to six months in jail on two counts of dangerous driving and one of criminal damage following a "road rage" attack on another motorist's car.[6] At the same time, he was banned from driving for three and a half years.[7]

On the death of his father in 2014, the Oxford Mail noted the new duke's "well-publicised drug addiction" and reported that a spokesman for Blenheim Palace had said "the Palace will remain under the control of trustees", but that the 12th Duke could himself become one of the trustees.[8] The Daily Telegraph reported that "The responsibility of maintaining one of Britain's grandest country houses for future generations now passes to 58-year-old Jamie Blandford, as he is commonly known, following a remarkable turnaround in his relationship with his late father, who once described him as the 'black sheep' of his family."[9]

On 24 June 2009, he appeared in a BBC Television documentary, Famous, Rich and Homeless, in which famous people were filmed spending three nights in the open with nothing but a sleeping bag, though he refused to "sleep rough". He claimed that on the first night he slept in the car park of a five-star hotel, though his sleeping bag was discovered unopened, and on the second night he demanded to be housed in a hotel. He refused to participate further despite giving an assurance that he would sleep rough on the third night, and ended his participation on that night. Another participant, Hardeep Singh Kohli, said that Blandford's behaviour was "disrespectful to all the people out there".[10]

His first wife was Rebecca Mary Few Brown (born September 1957, Bangor, Wales). They were married on 24 February 1990 at the Church of St Mary Magdalene, Woodstock. Their marriage ended in divorce in 1998. They had one son, who is now heir apparent to the Dukedom of Marlborough:

• George John Godolphin Spencer-Churchill, Marquess of Blandford (born 28 July 1992), who went by the courtesy title Earl of Sunderland until his father's accession to the dukedom in 2014.

His second wife is Edla Griffiths (born 1968, Abergavenny, Wales), whom he married at Woodstock Register Office on 1 March 2002. They have two children:

• Lady Araminta Clementine Megan Spencer-Churchill (born 8 April 2007)
• Lord Caspar Sasha Ivor Spencer-Churchill (born 18 October 2008)

Lord Caspar Spencer-Churchill is second in the line of succession to the Dukedom of Marlborough.
