Conservative party leader David Cameron told the British Press Association parenthood should not be something the teenagers should even have been contemplating.
Former Conservative party leader Iain Duncan Smith, who runs the Centre for Social Justice think tank, told PA the birth highlighted another case of "broken Britain" where "anything goes."
"It's not being accusative, it's about pointing out the complete collapse in some parts of society of any sense of what's right and wrong.
"There is no opprobrium any more about behavior and quite often children witness behavior that's aggressive, violent, rude and sexual. It's as if no one is saying this is wrong."
Prime Minister Gordon Brown said "all of us would want to avoid teenage pregnancies," PA reported.
Tony Kerridge, of the sexual health specialist Marie Stopes International, told PA children needed better education.
"We have got the social aspect of young girls in the UK seeing having a baby as a route to getting their own place," he said.
