More professional wheelchair tennis events will take place at ATP and WTA tournaments next year following the approval of a new calendar structure by the International Tennis Federation (ITF).
While the specific events have not yet been confirmed, the ITF said a "significant number" of new ones will take place at ATP and WTA tournaments, creating a calendar including "higher standards" and "elevated prize money".
The four Grand Slams currently have both wheelchair and non-wheelchair events, in addition to six ATP and and WTA tournaments.
Great Britain's Alfie Hewett - a 33-time Grand Slam champion across singles and doubles - said the expansion presents a "great opportunity for players to take their careers to the next level".
