Political activist group Climate 200 will raise funds to enable teal MP Nicolette Boele to fight a legal challenge by the NSW Liberal Party to her nail-biting victory in the northern Sydney seat of Bradfield.

Boele, who will be sworn in as an MP when parliament sits next week for the first time since the May 3 election, said the challenge by Liberal candidate Gisele Kapterian was in accordance with due process.
