Bob Hawke leaves hospital after 'fall'

Former Australian prime minister Bob Hawke has left a NSW hospital after medical staff thoroughly checked for any problems arising from a fall.

Mr Hawke, 88, spent several days undergoing tests in Sydney's Royal North Shore hospital after reportedly being admitted on Saturday.

He was discharged on Wednesday afternoon but had not returned to his residence, his office said.

"Mr Hawke expresses his gratitude for the abundance of good wishes sent by friends, colleagues and strangers from all over the world," a spokeswoman said in a statement.

Mr Hawke would continue with rehabilitation but his health was "fine", they added.

His daughter, Sue Pieters-Hawke, shed more light on the concerns.

"He's got a condition in his feet which means walking is sometimes a little bit difficult for him, which means he's a bit vulnerable to a bit of a fall," she told the Seven Network.

The former prime minister reportedly hit his head after falling at the weekend and underwent "rigorous" checks.

Mr Hawke served as Australia's 23rd prime minister from 1983-1991 and led Labor to four consecutive election victories.
