Macquarie Bank deputy chairman Mark Johnson has resigned from the bank. His resignation comes just weeks after chairman David Clarke stepped down.
Johnson also retires as chairman of the Macquarie Infrastructure Group, but will remain on the Macquarie Bank board until after July's annual general meeting.
Clarke said Johnson's contribution to the board had been "immeasurable".
Johnson joined Macquarie Bank's predecessor, Hill Samuel, in 1971 as joint managing director with Clarke. He left Australia to join Hill Samuel's London office in 1977.
In 1981 he returned to Australia and became founding director of Australian Bank until 1986, when he rejoined Macquarie Bank as chairman of corporate services. He was appointed to the board in February1987.
"I have had 40 years in the banking industry and it is time for me to leave. I will regret leaving Macquarie where I have enjoyed my business life and where I have many friends," he said.
