Colin Craig defamation trial On 23 September 2016, Bradbury testified as a defence witness in Jordan Williams' defamation trial against
Colin Craig, the former leader of the
Conservative Party. Williams, the co-founder of the
New Zealand Taxpayers' Union had filed a defamation suit against Craig after the latter had produced a pamphlet entitled "Dirty Politics and Hidden Agenda" attacking Williams, the right-wing blogger
Cameron Slater, and a dissident Party member John Stringer. In his testimony, Bradbury alleged that Williams had embarked on a political hit job against Craig and defended Craig's pamphlet. Bradbury described the trial as "an angry fight between two people who don't like each other much." Bradbury was also questioned by Williams' lawyer Peter McKnight for making alleged defamatory comments against Williams in
