The Centre for Social Justice (CSJ) has condemned the Government's lack of action in failing to stem what it called an "epidemic" of family breakdown.
Director of the CSJ, Christian Guy, said:
There are many misguided reasons for such political paralysis. Some argue that it is no business of politicians to meddle in the personal family choices people make.
Others suggest that rising family breakdown is just a modern process, an inevitable trait of human advancement. Others say family instability doesn't matter.
This has to change. Our political discourse about family policy must mature. Family breakdown is an urgent public health issue.
Backing commitment and setting a goal of reducing instability does not equate to criticising or stigmatising lone parents or those involved.
