A Portsmouth family group leader warned better sex education was not the answer in combating spiralling numbers of pregnancies outside of marriage.
Eileen Jones, the joint co-ordinator of Portsmouth Area Family Concern, spoke after figures showed one in three births were outside wedlock.
Also, 90 per cent of pregnant teenage girls were unmarried.
A report from the Office of Population Censuses and Surveys showed a continuing ‘dramatic’ trend in which 44 per cent of conceptions were by single women – in 1981 it was 29 per cent.
The proportion of single pregnant women who married before their baby was born had halved over the same period.
Mrs Jones said: ‘Sex education has not given children any moral framework.
‘It just says “do it when you want to”.’
