NEARLY half of housing workers dealt with tenants threatening suicide last year over the so-called 'bedroom tax'.
Wentworth and Dearne MP John Healey revealed the shocking claims and demanded an apology for the 'concern and chaos' caused by the government.
Last week, the Department for Work and Pensions admitted thousands of people had been wrongly paying bedroom tax and were entitled to a refund - because of a government mistake.
It means around 400 families in Rotherham and Barnsley could get back as much as £700.
Challenging Iain Duncan Smith in the House of Commons, Mr Healey said: "The news last week is a clear admission that thousands of people have been illegally hit with the bedroom tax since April.
"The latest survey from the Northern Housing Consortium says that nearly half of all frontline housing workers have dealt with someone who has threatened to commit suicide.
"This is largely because of the government's welfare changes."
Mr Duncan Smith said the department was 'sorry' but blamed the complex housing benefit regulations left by Labour.
