Ed Miliband said:
"Nine months ago, I asked Denise Kingsmill to lead an independent review to better understand and tackle exploitation in the care sector.
"Her report today shows that the army of care workers, who carry out some of the most important work anyone can do looking after parents, grandparents and the most vulnerable in our society, are often exploited with real consequences for those they care for.
"I have already set out detailed policy to strengthen the enforcement of the National Minimum Wage and end exploitation of zero hors contracts.
"I know that councils are under enormous pressure from reductions in central government funding But I am also determined that a Labour government will call time on clock-watch care. We will work with councils and care providers to end this practice."
