Farm slavery in East Anglia, Seals on salmon farms, Lord Henry Plumb

As Norfolk Police hosts a conference on human trafficking and modern slavery in rural areas of East Anglia, we ask how significant the problem of slavery is in this agriculturally important region.

All this week on Farming Today we've been looking at pests and predators, on the land, in farm buildings and in the air. But fish farms too have their own range of predators, and the methods the industry uses to deal with them can be controversial. Nancy Nicolson visits a salmon farm on the west coast of Scotland.

And we hear from Baron Plumb of Coleshill - Henry Plumb - one of the elder statesmen of British farming. In the 1970s, as President of the NFU, he helped steer UK farmers into the Common Market. Later this month he turns 90, and he tells Caz Graham about his long life in farming.
