Mr Lewis, who heads the camp for children aged 3 to 14 years old, said there would be more information available “in due course”.
Last night, parents received an email which read: “We regret to inform you that LL Camps will be closed for the summer with immediate effect.
“We understand that this will cause significant inconvenience to you and we are exceptionally apologetic for this.
“We cannot disclose any further information at this time and we appreciate your patience in this matter.”
An Ofsted spokesperson said: “We can confirm we have suspended the registrations of these early years settings while investigations are carried out. It would be inappropriate to comment further while investigations are ongoing.”
One mother said that parents who sent the children to camp were “totally stuffed” as a result of the sudden closure, adding that “hundreds of people were without summer childcare”.
The camp is said to be in the process of applying for free school status.
