"When it comes to joining the EU, I know what I’m talking about. In the 1970s, I was a member of the team in London that negotiated Britain’s accession. Later, in the European Commission in the 1990s, I was one of the architects of the enlargement of the EU from 12 to 15 members, and from 15 to 27. I also had a hand in writing the ‘Copenhagen criteria’, which the EU uses to judge prospective members."
