The Prime Minister's chief of staff appears to be keeping the option of a career in politics alive, saying she "has no intention of running for Parliament at this time".

This follows speculation within the Liberal Party that Peta Credlin will leave her role in Tony Abbott's office to take a seat in the Senate or House of Representatives ahead of the 2016 election.

Amid tensions between Mr Abbott's office and government MPs, it has been suggested that Ms Credlin could either take stood aside Assistant Treasurer Arthur Sinodinos' NSW Senate seat or Social Services Minister Kevin Andrews' safe Melbourne seat of Menzies in the event either retired - although neither have said they will retire.

Mr Andrews has said he intends to run again in 2016.
