Porirua Mayor Nick Leggett believes there is a "purge" going on within Labour to rid itself of members considered "right wing."
He takes issue with Labour leader Andrew Little's description of him yesterday as "right wing" and says he is a "moderate."
"I supported and continue to support a capital gains tax as a policy. Andrew Little doesn't. Who is more right wing?" he said.
"I believe I'm of the centre-left, however within Labour I have always been a moderate," Leggett told the Herald.
He said he was "pro-enterprise" but as mayor of Porirua, he had also been a strong advocate for social issues in the city.
