Fans will no longer need to use pen, paper and a stamped addressed envelope to apply for Wimbledon tickets after the grass-court showpiece announced an end to a 95-year tradition.

The move to an online ballot from 2020 was among several changes confirmed by the All England Club on Tuesday.

Prize money will increase by 11.8% this year, with the total pot at the Grand Slam standing at £38m.

The men’s and women’s singles champions will win £2.35m, a rise of £100,000.

Prize money for early-round losers will increase by more than 10%, while there is also a double-digit increase for men’s and women’s doubles.

The new retractable roof over Court One will be in operation this year but the shot-clock – used at January’s Australian Open – will not be.

But the device, which counts down the seconds allowed between points, is “very likely” to be introduced from 2020, All England Lawn Tennis Club (AELTC) chief executive Richard Lewis told a news conference.

Meanwhile, the wheelchair event has been expanded to include quad singles and doubles after a trial last year.

This year’s grass-court Grand Slam runs from 1 to 14 July.
