London's Natural History Museum will be unable to compete as one of Britain's
leading tourist attractions without more funding, a report has warned.
The museum is a major draw for overseas visitors
Academics said inflation-proof government grants alone would not protect its long-term future.
The museum relies on a £38m government grant, and director Sir Neil Chalmers said there were "alarm bells" over its ability to compete with other venues.
Each year the museum attracts three million visitors.
NATURAL HISTORY MUSEUM
Built in 1881
Employs more than 300 scientists
More than three million people visit each year
Adds £190m annually to the UK economy
Last year's turnover was £52m
UK's fifth most popular free visitor attraction
The museum commissioned the report - by experts from the London School of Economics and Imperial College - in order to draw attention to its "value to the nation".
It said the museum - which is free to enter - would not be able to compete adequately with private facilities that charged for entry.
"The resources of the (museum) will have to be able to increase at least in line with leisure expenditure in the wider market," it said.
Its annual government grant includes an extra amount to compensate for the introduction of free visitor entry in 2001.
Director Sir Neil said: "The nation should be proud of what the museum is achieving despite an ever-changing and increasingly competitive environment."
