The centre, which was managed by Solent University since 2010, was closed last December by the former Conservative-run council because of the condition of the building, which required significant repair, and declining user numbers.

The reversal of the previous decision to close the venue has been a priority for the new administration.

“I am so proud that we have been able to reopen this much-loved and much-needed leisure centre so quickly, just a couple of months after our new administration took control of the council in May,” said councillor Lorna Fielker, cabinet member for adults, health and leisure.

A recent consultation found that 86 per cent of respondents said that closing the venue would have a negative impact.

“We know from feedback we received during the recent consultation that this leisure centre means a lot to the local community and the groups who used it. I am delighted we will now be able to reopen this community asset and work together with the community and Active Nation to ensure St Mary’s Leisure Centre delivers the best outcomes and value for users,” said Councillor Toqeer Kataria, cabinet member for communities.

“Now we have achieved our short-term plan of getting St Mary’s Leisure Centre reopen, we can focus on the long-term plan to secure the venue’s future by working in partnership with the local community to establish what that looks like.”
