The NSW Labor conference is expected to back a proposal to give rank and file members voting power on who becomes state leader.

The NSW Labor Party is expected to adopt reforms aimed at empowering rank and file members over factional bosses.

The ALP state conference will over the coming weekend vote on a proposal to allow its ordinary members a say in choosing the party’s NSW leader.

Under the plan, which is expected to be supported by delegates, leadership can be determined by a ballot weighted at 50 per cent caucus members and 50 per cent members of the party.

Public debates between candidates would also be held under the proposal.

NSW Labor general secretary Jamie Clements said the plan, if supported, would be the most significant reform undertaken by the party for more than 75 years.

Queensland Labor has already given its members a say in choosing its state leader after former prime minister Kevin Rudd brought in similar reforms at a federal level in 2013.

Meanwhile, delegates at the NSW Labor conference will also consider a plan to let ordinary members choose the party’s Senate and Legislative Council candidates.

Currently, the state conference decides who ends up on its upper house tickets.

Delegates are also tipped to call for federal Labor to formally adopt former foreign minister Bob Carr’s position on Palestinian statehood.

A concerted caucus campaign by Mr Carr forced the Gillard government to abstain from a United Nations vote on granting the Palestinian Authority observer status.

The NSW Liberal Party’s State Council will also be held on Saturday in Sydney.
