The Common Agricultural Policy (CAP) has delivered production of affordable food and supported the farming and rural community for most of the six decades of the EU’s existence. At the beginning, it was confined to a limited trade arrangement between six European countries, growing to nine when Ireland, Denmark and the UK joined in 1973. Further expansion brought the EU up to 15 and finally 28 members with the collapse of communism in eastern Europe. The community is now at an advanced level of integration that has brought its own problems, best demonstrated by the UK deciding to leave putting a premium on national sovereignty.
