Jones, the barrister appointed to defend former Iranian Ambassador Hadi Soleimanpour is one of Britain`s leading experts on extradition, IRNA reported from London.

Prosecuting lawyer, acting for the Crown Prosecution Service on behalf of the controversial Argentinian request, Robert Bland, described Jones as the man who "wrote the book" on extradition during second hearing of the Soleimanpour case in London Friday.

Since being called to the Bar in 1972, Jones has handled fourteen full House of Lords appeals in extradition cases, including acting in 10 for foreign governments.

The most publicised was when he led the Crown Prosecution Service team acting on behalf of Spain`s extradition application against former Chile`s former president Augusto Pinochet between 1998 and 2000.

According to his practice, Jones is a specialist in criminal law, including commercial crime and international criminal law as well as on extradition.

In 1996, he was admitted into the US as a foreign advocate to support the defence in an irregular case of extradition from Mexico to face the death penalty.

Jones has given general advice on extradition matters in Japan, Australia, New Zealand, India, the Caribbean and throughout western Europe.

He has appeared in major disaster, terrorist and major fraud trials and authored a book, `Jones on Extradition and Mutual Assistance,` first published in 2000.
