Sydney: Cricketer Steven Smith was Friday named Australia's new Test captain to replace Michael Clarke, who will retire after the current Ashes series, Cricket Australia said.

David Warner, 28, will be the Test team's vice-captain.

‘When Michael made his decision to retire last week it was a very straightforward decision for us to nominate Steve as his successor,’ chief national selector Rod Marsh said in a statement.

‘He has big shoes to fill but everything about him suggests he is the right man for the job. At 26, he is a fine young man with extraordinary talent, excellent leadership qualities and a terrific temperament.’

Smith will also be Australia's T20 captain during their tour of the British Isles due to Aaron Finch's injury.
