VANCOUVER - Premier Gordon Campbell denies there's been any political inference in the corruption trial of two former B.C. government aides.

The defence in the trial has accused Campbell of interfering in the handling of documents related to the case -- documents the defence has been trying to get its hands on.

They say last May, Campbell appointed the deputy attorney general to handle documents that had previously been dealt with by a cabinet secretary.

Defence lawyer Kevin McCullough calls that decision "troubling'' and he wants Campbell to testify about it.

But Campbell denies any meddling, saying the case is "unfettered'' by any political interference.

A B.C. Supreme Court judge has agreed to allow the defence to submit questions on the issue to determine whether Campbell should testify in the trial of former ministerial aides Dave Basi and Bobby Virk.

They face breach of trust and fraud charges in the privatization of B.C. Rail in November of 2003, which triggered a raid on the B.C. legislature a month later.
