The Fur Farming (Prohibition) Act 2000 and the Gangmasters (Licensing) Act 2004 were passed by urban MPs with little thought.
The closing of fur farms was mere political malice, to make a gift to irrational protestors who had supported Labour's election campaigns. It put the farmers involved out of business for no reason, and enriched foreign farmers to whom the business moved.
Gangmaster licensing was passed in a moral panic after a media campaign, but it simply imposes the iron face of the state into what had been friendly and informal agriculatural relations. It adds a layer of bureaucracy and cost which ultimately comes out of the farm labourer's wages. Abusive gangmasters are few, and ignore the Act anyway. There are better ways to deal with the occasional abuses.
