Finance Minister Mathias Cormann has rejected suggestions he was the commander in chief of Peter Dutton's campaign in the August Liberal leadership spill.
Finance Minister Mathias Cormann has rejected a suggestion he acted like a "political Judas" during last year's Liberal leadership spill.
Senator Cormann has been described by some Liberal MPs as the "commander in chief" of Peter Dutton's insurrection campaign against ousted prime minister Malcolm Turnbull.
"It was a difficult week," Senator Cormann told ABC Radio on Monday after he was asked if he was a "political Judas".
"I made decisions based on what I felt was right, on the basis of what I thought was necessary, and in the best interests of the country and the government and the Liberal Party."
Former foreign minister Julie Bishop labelled him "the ultimate seducer and betrayer" of Mr Turnbull, according to a book written by political journalist Niki Savva.
