The museum, based in Bradford, West Yorkshire faces a ‘potentially devastating £900,000 budget shortfall,’ according to a report in local newspaper the Telegraph and Argus.
The news comes less than a year since the Government signalled that the museum had been saved from an earlier budget crisis.
Bradford South MP Gerry Sutcliffe told the Telegraph and Argus: ‘The future of the museum is again in jeopardy, because it faces a potential revenue shortfall of £900,000 a year.
‘That means we need to work with the Science Museum Group, the Government and the Council to find a way forward.’
However, a museum spokesman today told Amateur Photographer that the cut is ‘not a new budget reduction’.
But the spokesman refused to comment on what was discussed at a recent meeting with MPs.
In 2012, the NMM launched a spending review as part of a restructure designed to cut running costs after visitor numbers halved over the previous 10 years.
On Tuesday, a spokesman told AP it had no further news to report on the museum’s ongoing restructure.
