Former NSW planning minister Frank Sartor says he feels cheated, claiming Premier Nathan Rees has made a mistake in dropping him from the front bench. 

The bloodletting continued in NSW Labor ranks today, with Mr Sartor becoming one of three high profile casualties, joining Michael Costa who was dumped on Friday, and Reba Meagher, who last night ruled herself out of contention before she could be pushed. 

NSW right faction powerbroker Joe Tripodi's financial credentials have been given a glowing endorsement by Mr Rees. 

But Labor sources say the small business and ports minister is not an automatic choice to replace dumped Michael Costa as treasurer.
