Care firms have cancelled contracts with 95 UK councils, saying they cannot deliver services for the amount they are being paid, a BBC Panorama investigation has found.
Some firms said they could not recruit or retain the staff they needed.
The Local Government Association said it was the result of "historic under-funding" and an ageing population.
The government declined an interview but said English councils had received £9.25bn for social care.
...........According to the research, carried out for Panorama by Opus Restructuring and Company Watch, 69 home care companies have closed in the last three months and one in four of the UK's 2,500 home care companies is at risk of insolvency.
Despite the Tory promises not to raise taxes at the last election, there are only two ways out of this care home crisis - either the government has to borrow more money or raise taxes to fund these vital services. Cuts have gone too deep already and it's obvious austerity isn't working.
