HARARE - Lawyers for Zimbabwean opposition politician Roy Bennett asked the High Court on Monday to drop terrorism charges against him in a trial which has raised tensions in Harare's fragile unity government.

Bennett, a member of the Movement for Democratic Change and close ally of Prime Minister Morgan Tsvangirai, faces a possible death sentence if convicted of illegal possession of arms for purposes of committing terrorism, sabotage and banditry.

The prosecution's case -- that Bennett planned to fund a 2006 plot to blow up a major communications link and assassinate key government officials -- hinges on emails that prosecutors say link the former commercial farmer to the crime.

Mtetwa has said the e-mails could have been created by anyone to implicate Bennett.

Bennett claimed that he is being persecuted by President Robert Mugabe's ZANU-PF party to stop him from taking up the post of deputy agriculture minister.

State prosecutors on Thursday are expected to ask the court to reject the defence's application to drop the case and, instead, ask Bennett to take the stand.
