The pressure of looking after children while caring for elderly relatives is taking its toll on all aspects of family life, a Carers UK survey suggests.

It found that a third of "sandwich carers" had to give up work, while two-thirds said their marriages had been damaged.

The charity is calling for care services and employers to support the 2.4 million families in this situation.

About 1,000 carers were surveyed.

Four in ten said they were struggling to cope with the demands of caring for children under the age of 18 and an older or disabled adult at the same time.

More than half juggled work and caring for their dependents, but some had had to give up work completely.

For those who continued to work, they reported feeling stressed and tired while doing their job.
