Ever since Margaret Thatcher launched the most destructive British premiership in modern history by quoting St Francis of Assisi, I’ve been wary of politicians who arrive waving olive branches. So when David Cameron, in the words of the Conservative Party, promises ‘to shake up the tax and benefits system to boost marriage as part of his campaign to mend Britain’s broken society’, I don’t sense the glimmer of a new dawn. David Cameron, too, has made encouraging noises about devolving power and responsibility. The right role for the rest of us is to help them do their jobs better.
