George Eustice MP (Conservative agriculture minister from 2015 to February 2019) in The Guardian:
The Conservative party had a manifesto commitment to promote British values on animal welfare through any future trade deals we might strike. A modern trade deal is not simply about commerce, it is also about values. There is currently a cross-party consensus that we should enshrine the recognition of animal sentience in statute to underpin all our existing policies and inform new ones. One option might be to suggest that the US introduce a similar piece of legislation at federal level to drive the modernisation of its own laws. We could even send British advisers to Washington to help them do it as part of our trade negotiations.
The international trade secretary, Liam Fox, understandably wants to talk about opportunities for new industries such as services or digital but, in the court of public opinion, if the choice is between the commercial interests of banks or the welfare of chickens, the chickens will win every time. The sound of clucking chickens will never be far from the negotiating table, tugging at our consciences so we might as well get used to it. Unless we deliver on our manifesto commitment, we will give free trade a bad name. We should use the power of the UK to project British values of kindness and compassion in any future trade deals.
My emphasis. Eustice is a brexiter. He wants to leave the EU and sign independent trade agreements. Does he seriously think the prospect of signing a trade deal with the UK will move the US to overturn decades of agricultural lobbying and implement decent animal welfare regulations?
