“All activities including swimming lessons are also suspended until further notice.
“This also extends to community based Active Sefton sessions and the Easter Be Active Programme.

“However due to recent government guidance, these temporary arrangements are crucial to help in the next phase of the government’s plan to tackle the outbreak.
“It is still very important to remain as active as possible during this time. We will do our absolute best to provide helpful hints, tips and guidance for residents via our social media channels and recommend that residents remain active at a social distance utilising the outdoors where possible.
