"Early in his book [The Road to Somewhere], Goodhart tells the story of sitting between Gus O’Donnell, head of the Civil Service, and Mark Thompson, director-general of the BBC, at an Oxford college dinner in 2011. O’Donnell said that at the Treasury, he supported mass immigration because he believed his job was to maximise global welfare, not national. Thompson emphatically agreed."
From this interview with David Goodhart at Policy Exchange.
Lord O'Donnell, as he now is, was brought up a strict Catholic and once contemplated becoming a priest. I suspect the universalism taught him at his Catholic grammar school lies behind his views on immigration, as it does behind that of the extreme immigration enthusiast Peter Sutherland, who was educated by Jesuits. Mr Sutherland, a former European Commissioner, thinks EU should "do its best to undermine" the "homogeneity" of its member states.
"All questions are ultimately theological" said Cardinal Manning and a lot of Europe's problems are based on bad theology, of which the churches these days are full.
