Sir Martin Sorrell, the founder and chief executive of WPP, was awarded one of the largest pay cheques in British corporate history last night after he received a share package worth GBP62.8 million. In a statement, the group said that Sir Martin was cashing in GBP30.2 million immediately to discharge the “consequential tax liabilities.” Taking the WPP chief’s salary, pension payments and short-term bonuses into account, his total pay package for last year is likely to hit GBP70 million.
