Younis' main focus will be to bolster Yorkshire's Championship batting line-up at a time when the defending champions expect to lose several players to England for the Test tour of the West Indies in April and May. He will be available for the Championship opener against Worcestershire at New Road on April 12, Cricinfo reported.

Martyn Moxon, Yorkshire's director of cricket, said: "We have been looking for a world-class batsman to strengthen our batting department at the start of the season. Younus fits the bill and will add real quality to our top-order.

"It also helps that he understands the culture of the club and what it means to play for Yorkshire. That was a major factor in signing him. We hope his vast experience will enable us to continue our efforts from last year and give us a great opportunity to get off to a winning start in the Championship campaign."
