Yesterday Tennis Europe and the ITF released statements revealing a route map at last for the return of competitive junior events. Tennis Europe has the more detailed statement - planning to start from August 31 with lower grade events, but no Grade 1 or Super Category for the time being and no under 12 events until January.
The ITF statement gives less detail, but has the same provisional start date (albeit with a few of the scheduled tournaments that week already cancelled).
The LTA under 12/14 nationals scheduled for August have been cancelled.
