There is a big discussion at the moment around the Crown estate in Wales and whether the money generated from it should be given to the Welsh Government to spend in Wales.
A petition on Change.org has now been signed by more than 11,000 people calling on the "transfer of control over the £500m Crown Estate to Wales". The petition reads: "This is money that would enable Wales to build and develop our own Welsh renewable energy industry rather than selling off our assets to the highest foreign bidder."
But what is the Crown Estate? And what would this mean for Wales? To answer these questions we will be drawing from the conclusions of Lorna Scurlock from Senedd Research.
