The Charity Commission is looking into "serious concerns" about a heritage plaque charity after a fundraising lunch organised in memory of the singer George Michael was cancelled.
The Heritage Foundation, which puts in place memorials to and blue plaques about deceased public figures, was supposed to hold the lunch on 15 April, but it was cancelled.
No new date has been set for the lunch and it has been reported that 200 people paid £90 each to attend the event.
The lunch would have seen a blue plaque of Michael unveiled at his former sixth form at Bushey Meads School in Hertfordshire.
In a statement on the charity’s website, David Graham, chair of the Heritage Foundation, said his "present medical condition" had forced the cancellation.
"This has been done with great reluctance and I apologise for any inconvenience and disappointment this has caused," the statement said.
"This tribute lunch to the late great George Michael will take place on a new date in the near future TBC.
"It is my belief that the plaque unveiling is still going ahead."
The Heritage Foundation’s funds are distributed by the charity the Arts and Entertainment Charitable Trust, which had an income of £2,000 in the year to 30 April 2017, according to the Charity Commission website.
In a statement, the Charity Commission said: "We are aware of serious concerns regarding the Heritage Foundation, which is run by the Arts and Entertainment Charitable Trust.
"We are currently analysing information to assess the risks and concerns which may require regulatory action."
