Campaigners are calling for the Merchant Venturers to hand over Clifton Down to the city of Bristol and for them to be booted off the statutory body that manages it.
Clifton Down is equivalent in size to just over 130 football pitches and makes up half of The Downs, a huge public common in north Bristol.
It is owned by the Society of Merchant Venturers, an ancient trading organisation in Bristol, which - along with Bristol City Council which owns the other half - sits on the statutory committee that manages The Downs.
