Business and Politics don’t mix? They do if you’re a professional lobbyist who is also a Liberal Party factional leader with the power to influence (and sometimes overtly control) the selection of members of parliament who can then be approached on behalf of the lobbyist’s paying customers. And they do if you’re a ranking Labor politician whose ability to open political doors and influence people appeals to the big end of town where so many of them have found a comfortable corporate home after their political lives have run their course.
