* SIMON MANN:

-- Educated at the exclusive Eton public school, Simon Mann is a former army officer turned mercenary who has already served four years in a Zimbabwean jail after being found guilty of trying to buy weapons for the alleged plot.

-- Mann is a descendant of a brewing family who accumulated wealth and influence in the mid-20th century. His father George captained the England cricket team in the 1940s as his father had before him in the 1920s.

-- Simon took a different route. A South African citizen with a home in the plush Cape Town neighbourhood of Constantia, he worked with former mercenary groups Executive Outcomes and later with Tim Spicer's Sandline International.

-- Mann was arrested at Harare airport in March 2004 with a plane load of weapons and men. He said they were heading to the Democratic Republic of Congo to provide diamond mine security.

-- Other alleged coup plotters were detained in Equatorial Guinea, casting doubt on the alibi, and Mann was tried and found guilty of violating Zimbabwean immigration, firearms and security laws and sentenced to seven years' imprisonment.

-- In May 2007 a Zimbabwean court ruled that Mann could be extradited to Equatorial Guinea to stand trial for the coup plot and, although he fought the ruling on the grounds that it would be a death sentence.
