'Hidden army' of elderly carers, says Age UK

The number of people in their 80s or older who are relied on as carers has rocketed in the last seven years, according to a charity.

Age UK says one in seven of the "oldest old" - an estimated 417,000 people in all - now provides some sort of unpaid care to family or friends.

Many are exhausted and say they worry about how long they might be able to carry on, says the charity.
