Australian Prime Minister bans sex amongst staff following 'shocking' affair

Australia's prime minister has banned his ministers from having sex with staff as his deputy battled for political survival over revelations that he is expecting a baby with a former press secretary.

Prime minister Malcolm Turnbull accused Barnaby Joyce of making a "shocking error of judgment" by having an office affair which had hurt his wife, his four daughters and his new partner, who is due to give birth in April.
