Alleged Costello comeback sparks infighting

Quote from the above news report:

"The ABC has learnt the Federal Coalition is being rocked by claims former treasurer Peter Costello made a bid to return to the political stage late last year."

"The ABC's 7.30 program has found bitter factional in-fighting was triggered by the purported move by Mr Costello, who demanded a young MP step aside to accommodate him"

"The dispute has laid bare the deep divisions in the Liberal Party’s Victorian branch, which threaten the Coalition at a time when it believes government is within its grasp."
