CANBERRA, Aug 23 (Reuters) - Embattled Australian Prime Minister Malcolm Turnbull is unlikely to contest a second leadership ballot, making way for Treasurer Scott Morrison as a surprise challenger for the top job, Sky News reported on Thursday.
Turnbull narrowly won a party-room vote on Tuesday by 48 to 35 against former home affairs minister Peter Dutton. But the unconvincing victory left him vulnerable to another challenge.
Dutton called for a second ballot on Thursday, while three senior ministers backed the call, saying Turnbull had lost the majority support of the ruling Liberal party.
