TTIP, Cameron and Johnson on EU referendum, Struggling dairy farmer

As negotiations continue into a controversial trade deal between the EU and the United States, we ask how it would affect UK farmers.
The Transatlantic Trade and Investment Partnership - or TTIP - is the largest bilateral deal ever negotiated. It aims to lower trade tariffs between the two areas allowing for more trade. But concerns include how agricultural sectors here will be protected from practices used in America, that are banned here - for example feeding growth hormones to beef cattle, and washing poultry carcasses with chemicals. Today we hear from the EU's Agriculture and Trade spokesman what are the 'red lines' Europe won't cross in the search for an agreement.
