A former Conservative Party worker told the High Court at Auckland today that Colin Craig's former Press Secretary Rachel MacGregor was "possessive of Colin's time and forever fussing over him".
Angela Storr told the court that Ms MacGregor was controlling about how Craig "dressed, how he had his hair and how he posed for photos" and was trying to change his image.
Former Conservative Party leader Colin Craig is being sued for defamation by Taxpayers' Union founder Jordan Williams over comments made in a 2015 media conference and in a widely distributed pamphlet.
Craig is defending the case.
Ms Storr travelled regularly with Craig and Ms MacGregor for work and says she was "very close friends" with Ms MacGregor and has a "very close" relationship with Craig and his wife Helen.
She regularly shared hotel rooms with Ms MacGregor on work trips to keep costs down.
Ms Storr told the jury she was in the back seat of the car with Ms MacGregor on a trip from Hamilton.
Ms MacGregor was texting her boyfriend and Ms Storr read the text over her shoulder.
She says Ms MacGregor was telling her boyfriend that Craig was being horrible to her and yelling.
Ms Storr says that was a "blatant lie" and was so concerned she told Craig about it.
Ms Storr works for a company in which Craig is the director, but says there's no conflict of interest for her in this case.
The trial continues.
