The Kennedy Center has temporarily suspended its free public tour programme, according to reports citing an internal memo to volunteers. The move matters because the volunteer-led tours have been a longstanding way for visitors to access and learn about the Washington performing arts institution.

The pause took effect on Friday and follows scrutiny of changes at the Kennedy Center under its current leadership. A spokesperson said tour routes were being reviewed to ensure the best visitor experience, while reports said the programme had operated for more than five decades.
