Cymdeithas yr Iaith Gymraeg has attacked Tony Blair's asertion today that minorities in Britain have a 'duty' to integrate. Dafydd Morgan Lewis said on behalf of the Society:"This is a bare faced cheek when one considers that the English themselves are the worst people in the world at intigrating and accepting other people's cultures. We only have to look at their behaviour in France, Spain or Wales to recognise this. Tony Blair will not achiev social harmony in Britain by imposing English values on all its citizens."
