Yorkshire Sculpture Park, the National Coal Mining Museum for England and Hepworth Wakefield may join forces as part of a new organisation.

Peter Box, leader of Labour-controlled Wakefield Council, said discussions to establish a “creative trust” between the three organisations were in the early stages.

All three institutions receive funding from Wakefield Council. What form the new body will take remains unclear. The new partnership could also include the Theatre Royal in Wakefield.

Richard Dean, deputy director of Yorkshire Sculpture Park, said: “As some of the major arts organisations in the region, we are discussing the challenges facing us all, and we will continue to work together, as we have on many occasions in the past.”

A spokeswoman for the Hepworth Wakefield, which is opening next month as the largest purpose-built exhibition space outside London, issued the same statement.

Meanwhile, Margaret Faull, director of the National Coal Mining Museum for England, said: “No proposal has gone to my board of trustees, which met last week [early March], to enter into any formal arrangement, such as a trust.”
