More historic theatres across the UK are now under threat due to the recession, according to the Theatres Trust's latest Theatre Buildings at Risk (TBAR) register.

The trust has also warned that public spending cuts could lead to a further increase as plans to save buildings are put on hold and the risk of demolition grows. Derby Hippodrome; Wallsend's Borough Theatre and Workington Opera House are among the venues identified by TBAR as being most at risk from "imminent demolition".

However, the trust confirmed that some theatres have been taken off the list - such as Blackpool's Grade II*-listed Opera House and St George's Theatre in Great Yarmouth, Norfolk. The Theatres Trust is concerned that the government's decision to abolish regional development agencies will mean capital funding sources for theatres are now "unclear".

Trust chair Rob Dickins said: "I'm very concerned that the theatres currently providing local people with access to their only live arts and entertainment experiences are going to end up abandoned and lying empty. "Previously closed and abandoned theatres are also now more of a target for redevelopment and demolition. We cannot lose our theatre heritage in this way."
