Thatcher challenges coup interrogation

Mark Thatcher and his lawyers went to court today to wrap up their challenge to the legality of a South African subpoena to question him about a coup attempt in oil-rich Equatorial Guinea.

The 51-year-old son of former Prime Minister Baroness Thatcher, arrived at the Cape High Court with his legal team, appearing relaxed, and exchanging greetings with the throng of local and foreign media for the second day of the hearing.
