Mark McGowan has taken the stand in his defamation trial involving Clive Palmer, saying the billionaire's "deeply offensive" statements had contributed to death threats against him and his family.
Giving evidence on Monday in the Federal Court in Sydney, the West Australian premier said various public comments by Mr Palmer had left him "extremely angry", hurt and exasperated and caused him many sleepless nights.
Mr Palmer is suing Mr McGowan, claiming public comments - including labelling the Queensland businessman the "enemy of the state" - had damaged his reputation.
