The Citizens & Ratepayers leader on Auckland Council, Christine Fletcher, reportedly threatened to resign during a heated internal wrangle among right-leaning councillors on Mayor Len Brown's $2.86 billion inner-city rail loop.
Mrs Fletcher stayed on as leader, but is now offside with some centre-right councillors for making "nasty, personal comments" against councillor and former Act MP Penny Webster at last Friday's adoption of the Auckland Plan.
Former C&R Auckland City councillor Aaron Bhatnagar, who is advising Mrs Fletcher, is being blamed for the attack on Mrs Webster and negative tactics being adopted by the right.
Last night, Mrs Fletcher made no apologies for accusing Mrs Webster of abandoning her fiscal responsibilities and being in the pocket of Mr Brown, saying she had to own her vote as chair of the finance committee and a member of Mr Brown's inner circle.
"This is a robust environment we are working in," said Mrs Fletcher, a former National MP schooled in the bearpit of Parliament.
