NBN Co boss MIke Quigley jumps - but was he pushed?

After months of speculation, the embattled chief executive of NBN Co Mike Quigley has announced his resignation.

Mr Quigley, who was appointed to the role four years ago, will remain as CEO until a successor is appointed.

Significantly, Mr Quigley says he will "retire from corporate life" after coming out of retirement to build the National Broadband Network.

Mr Quigley has been plagued by political pressure and more recently has been criticised for delays in the rollout and disputes with contractors.
