From the UK Daily Mail:
Ministers must not ‘preach’ to parents about marriage or lifestyles, Nick Clegg declared yesterday – as he signalled a new Coalition rift on the family.
In a direct challenge to David Cameron he also dismissed the Prime Minister’s cherished plan for a marriage tax break – saying that Liberal Democrat tax reforms must come first.
… His comments stand in stark contrast to the views of Mr Cameron, who has repeatedly stressed the importance of marriage. In the run-up to last year’s election he said: ‘I just think as a society, saying that marriage is a good thing and celebrating it and encouraging it, including through the tax system, is something that most societies do in Europe. It's very sensible for us to do as well.’
