Prime minister David Cameron unveils plans to introduce 'troubleshooters' to tackle the UK's 120,000 troubled families:

"For many of the most troubled families, there will be a family worker – a single point of contact for the first time for particular families, working out what the family needs, where the waste is and lining up the right services at the right time.

"When the front door opens and the worker goes in, they will see the family as a whole and get a plan of action together, agreed with the family. This will often be basic, practical things that are the building blocks of an orderly home and a responsible life.

"These things don't always cost a lot but they make all the difference. And they will get on top of the services, sorting out – and sometimes fending off – the 28 or more different state services that come calling at the door.

"Not a string of well-meaning, disconnected officials who end up treating the symptoms and not the causes.

"But a clear hard-headed recognition of how the family is going wrong – and what the family members themselves can do to take responsibility."
