Conservative education spokesman Michael Gove will today blame "lad mags", such as Zoo and Nuts, for fuelling a rise in feckless fatherhood by encouraging young men to view women as sex objects.
Gove will use his speech on family and social mobility to call the magazines to account for the social impact of their celebration of "instant-hit hedonism".
He will link the popular titles - which sell around half a million copies a week to men aged 18-30, serving up topless photos, football and jokes - to the social problems of relationship breakdown and absent fathers.
And he will suggest that the drive to reduce teenage pregnancy should put more emphasis on making young men come to terms with their responsibilities.
