The LTA is “cautiously optimistic” fans will be able to attend its summer tournaments this year after the schedule was announced.

The grass-court season was cancelled in 2020 due to the coronavirus pandemic, meaning Wimbledon was not staged for the first time since the Second World War.

But the tournament will return this summer along with traditional warm-up events at Queen’s, Birmingham, Eastbourne and Nottingham over a six-week period in June and July.

The grand slam in London is the showpiece event of the grass-court season and will take place between 28 June and 11 July, with organisers saying last week they were preparing for it to go ahead in front of a reduced capacity.

“The national governing body’s intention is for the events to take place even if they are behind closed doors.”

The LTA chief executive Scott Lloyd says that due to current conditions, where players will have to form a bubble, costs of staging the grass-court season have doubled.

“It remains a very challenging time for the whole country, but we are cautiously looking forward to the summer and what we hope will be the return of the British grass court season,” he said.

“We face an uncertain picture in the months ahead and our priority must be the health and safety of the public and all those involved in staging our events.

“However our hope right now is that we will have some level of spectator attendance at all our events. We know how much fans want to come back, and the sport isn’t the same without them, so we are planning for their return and hoping that circumstances will make that possible.

“Staging events, especially those involving a large number of international competitors is exceptionally complicated at present, but we are working hard along with our partners to make this possible and provide the best preparation for The Championships, Wimbledon.

“The cost of delivering this planned calendar is double that of the grass court series hosted in this country in any normal year.

“Sadly this has meant that we have had to make some changes to our Trophy Series events, although we have also increased some draw sizes where we can.

“We will keep these arrangements under review over the coming months and remain committed to increasing the number of domestic events we stage in future years.

“Our focus is now on resolving the many logistical and operational challenges that remain so that we can all look forward to a summer of world class tennis in 2021.”
