Tillakaratne Dilshan will take over from Kumar Sangakarra as captain of Sri Lanka for next month's tour of England.
Sangakkara decided to step down after the team lost to India in this month's World Cup final.
"We are proud to announce the appointment of Dilshan as the national captain in all three formats of the game for the tour of England," Sri Lanka Cricket said yesterday.
"The national selectors have postponed the appointment of a vice-captain since the prospective candidates are nursing injuries and their availability for the forthcoming tour is still in question."
Opening batsman Dilshan, 34, was the leading run-scorer in the World Cup with 500 at an average of 62.50.
