London - Wimbledon has announced a 40 percent increase in prize money for this year's tournament and plans to build a retractable roof over Court No 1.
The All England Club says total prize money will be £22.6 million, an increase of £6.5 million from last year.
The club calls it is the largest single increase and biggest total prize money in the history of professional tennis.
The men's and women's singles champions will reach receive £1.6 million (R22.6m), up from £1.15 million (R16.2m) a year ago.
Wimbledon broke with tradition by installing a roof on Centre Court in 2009 so play can continue even during the often fickle British summer weather.
Chairperson Philip Brook told a news conference the design process would begin shortly, taking two years to complete before a three-year construction process.
