'Impertinent' Credlin question angers PM

Tony Abbott has dismissed as impertinent a question about the future of his chief of staff.

Some Liberals MPs want the prime minister to dump Peta Credlin, seeing her as the cause for many of the internal problems besetting the government.

When asked by Neil Mitchell on Fairfax Radio on Thursday whether he would change his chief of staff, Mr Abbott said: "Neil, that's an impertinent question - I don't ask you about the internal workings of your radio station."

He would not say whether he would accept Ms Credlin's resignation.
