Martin Parkinson is staying on as Treasury secretary until after November’s G20 Leaders Meeting in Brisbane.

Prime Minister Tony Abbott has asked Martin Parkinson to stay on as Treasury Secretary until after the G20 Leaders Meeting in November.

Dr Parkinson had been expected to stand down as the head of the department after assisting Treasurer Joe Hockey with his first budget in May.

Mr Abbott announced that Dr Parkinson was leaving Treasury’s top job soon after being sworn in as prime minister after the September election, raising speculation that Dr Parkinson had been pushed.

Australia is the G20 president this year, which will end with the Leaders meeting in Brisbane.

Mr Hockey will attend a G20 finance minsters and central bank governors meeting in Washington next week, and after what was regarded as a successful first meeting in Sydney in February.

Mr Hockey will host a further meeting in Cairns in September.
