The Minister for Planning, Rob Stokes was elected to Parliament in 2007, and handed his first ministry in 2014.
The member for Pittwater was considered a frontrunner to replace his good friend Mike Baird as premier when he resigned in 2017, but was overseas when the decision was made to appoint Ms Berejiklian.

Mr Stokes was at the forefront of the recent civil war that erupted within the Coalition over the government’s controversial koala planning policy.
Andrew Constance has endured a tumultuous 2020 in which he signalled his intention to resign after bushfires tore through his south coast electorate, before briefly throwing his hat in the ring to contest the federal seat of Eden-Monaro.
The 46-year-old Transport Minister has long held leadership aspirations and gained popularity during the Black Summer bushfires for openly criticising the Prime Minister’s handling of the crisis.
However, his move to contest a federal byelection in May blindsided some colleagues and damaged his long standing relationship with Nationals leader John Barilaro, who was also expected to run.

While regarded by some colleagues as “the man in waiting,” others believe it is too early for the 39-year-old to take the reins.
Mr Kean was first elected to the Legislative Assembly as the member for Hornsby in 2011, and was first elevated to a ministerial position in 2017.
While Mr Kean is the leader of the moderates, he does not control the totality of its numbers.
