Peter Dutton has ripped into former prime minister Kevin Rudd over his approach to Pfizer executives.
Mr Rudd contacted the pharmaceutical giant to secure fast-tracked shipments of vaccines for Australia.
He then wrote Prime Minister Scott Morrison a letter to brief him on the discussions, with a deal announced eight days later.
“I suspect it wouldn’t take our greatest detective within the Queensland Police Service to identify who leaked that self-serving letter,” Mr Dutton told 4BC radio on Monday.
“Kevin claims credit for many things, it used to drive his Labor colleagues crazy.”
The defence minister suggested Mr Rudd was inserting himself into the public debate because he was “bored to death in retirement”.
“I wouldn’t pay much attention to it,” Mr Dutton said.
