The board of NBN Co has offered to resign en masse, falling on their sword amid suggestions they do not have the confidence of the incoming government.

The chairwoman Siobhan McKenna submitted her resignation to the Minister for Communications, Malcolm Turnbull, along with the rest of the board. Former Telstra boss Ziggy Switkowski is waiting in the wings to be appointed executive chairman.

Kerry Schott is expected to be one of the only directors invited to stay on by Mr Turnbull, who has been highly critical of the board and the way the company has been run under the Labor government.
