Jonathan Powell (born 1947) is a British television producer and executive. After graduating from the University of East Anglia in 1968, he began working in television drama, producing programmes such as Crown Court.

He produced several drama series during the 1970s, including literary adaptations such as A Christmas Carol (1977) and Wuthering Heights (1978). However, probably his most famous work was as producer of the Alec Guinness-starring BBC serials Tinker, Tailor, Soldier, Spy (1979) and its sequel Smiley's People (1982).

In 1983 he was made Head of Drama Series & Serials at BBC Television, and later became the overall Head of Drama. His most prominent television post came in 1987 when he succeeded Michael Grade as the Controller of BBC One, the Corporation's premier television channel and the oldest station in the UK. He was held responsible for commissioning Eldorado, a new soap opera that lasted only a year and was critically and popularly regarded as a costly fiasco and an embarrassment for the BBC. He was also involved in the ultimate cancellation of the original series of Doctor Who in 1989.

He held this post until 1993, when he left the BBC to join the independent company Carlton Television, where he became Director of Drama & Co-Production. As of December 2005, he still holds this position.

Jonathan Powell (born 1969) is a British pianist and composer. He specializes in playing avant garde and Russian Romantic music.

He was educated at King's College, Cambridge, and was a student of Denis Matthews and Sulamita Aronovsky. He made his performing debut at the age of 20 in the Purcell Room in London.

His repertoire is broad and ranges from Bach to many contemporary works (he is associated with composers as varied as Finnissy, White, Ambrosini, Staud and Sirodeau). He specialises in the late Romantic era, and made his first acquaintance with Sorabji's music, with which he has since become strongly associated, in 1984 through the radio broadcasts of Yonty Solomon and through the scores that were then still published and available through Curwen. He was encouraged to contact the composer, and obtained copies of several later works which he premiered starting in 1990, and has been recording and performing regularly.

He has played Sorabji's whole Opus Clavicembalisticum at several public performances as well as other works of Sorabji, including the substantial Fourth Piano Sonata (1930). He has also recorded CDs, of Sorabji's music and of others', for the Altarus, Largo, Toccata, ASV and Danacord labels, including also works by Joseph Marx, Alexander Krein and Goldenweiser.

Samples of two of his own compositions can be heard at the British Music Information Centre page below.

Jonathan Powell (born 1956) served as chief of staff to British Prime Minister Tony Blair from his election in 1997 until his resignation in 2007. The official Downing Street website described his job as having "direct responsibility for leading and co-ordinating operations across Number 10". Despite his low profile, he was arguably Mr Blair's closest political aide. On 7 December 2007, Morgan Stanley announced that Powell would be joining the bank as a full time Senior Managing Director of its investment banking division .

The son of an Air Vice Marshal, Powell comes from a powerful family. His brother Lord Powell - formerly Sir Charles Powell - was foreign policy advisor to former Prime Minister Margaret Thatcher. Powell was educated at King's School Canterbury and subsequently studied history at Oxford University and the University of Pennsylvania, later working for the BBC and Granada TV before joining the Foreign Office in 1979.

Powell left the diplomatic service to work for Blair in 1995, while Blair was still Leader of the Opposition. After Labour's election victory in 1997, both Powell and Blair's high-profile Director of Communications, Alastair Campbell, took up the same jobs in Downing Street.

In the early years of the Blair administration, one of Powell's most crucial jobs was his role in the Northern Ireland peace talks which led to the Good Friday agreement. He has continued to be both a key right-hand man for Blair, as well as a trusted advisor on a wide range of policy issues. While much of the rest of Blair's 'kitchen cabinet' - including Campbell - departed before Blair's resignation, Powell remained in Downing Street until June 2007.

Powell's role in the Blair Downing Street came under close scrutiny during the Hutton Inquiry, held following the death of Dr David Kelly in 2003. Powell gave evidence to the inquiry on Monday August 18, and described several crucial meetings he had attended, at which Dr Kelly had been discussed before his name appeared in the media. An email sent by Powell to the JIC chairman John Scarlett in September 2002 was also highlighted, as it appeared to suggest a dossier on the threat posed by Iraq be toughenedblank">http://www.guardian.co.uk/hutton/keyplayers/story/0,,1027482,00.html. Many commentators criticised the style of government described by Powell as too informal, some dubbing it 'sofa government' as many meetings were held in relaxed surroundings, without proper notes being taken. The subsequent, and separate, _Butler Report also emphasised these criticisms. Both the Hutton and Butler reports indicated Powell was very close to Blair.

Powell has four children - two daughters with his partner, Sarah Helm, and two sons from a previous marriage.
