The event had been scheduled to run from December 5 to 6, but has now been moved until January 16 and 17 in 2021.

Organisers British Para-Swimming and Activity Alliance said the coronavrius crisis, and restrictions still in place to try and limit the spread of the virus, had accounted for the postponement.

Manchester Aquatics Centre remains the venue for the event.

"As we move into the new Paralympic year, we know that competition experiences are what we all love and need," British Para-Swimming performance director Chris Furber said.

"It’s fantastic to be working with our friends at Activity Alliance on this event again and we will be working hard in the background to ensure we can deliver a safe and fun competition environment for everyone within the Government’s regulations."

The National Para-Swimming Championships will only go ahead in January if the sport is able to progress through a phased return and fresh restrictions are not imposed by the United Kingdom Government.

The UK reported 4, 422 new COVID-19 cases yesterday - a four-month high.

"The National Para-Swimming Championships are an essential part of the Para-swimming pathway," added Activity Alliance chief executive Barry Horne.

"We know the important role such competitive events can play in athlete development. 

"But returning safely for participants, volunteers and officials is our top priority. 

"We are working closely with British Para-Swimming and within guidance to make sure everyone can return to a safe and enjoyable competition environment."

More than 320 athletes took part in the event last year.
