Self-employed workers from Wales fear they face financial ruin after becoming embroiled in a tax avoidance scheme.
One says she could face a bill of about £200,000, despite insisting she made no money from the scheme. Another fears losing his home.
At least 1,000 Welsh freelance workers could be affected by the government "loan charge" measure from April.
HMRC say that it is unfair to ordinary taxpayers to let anybody benefit from contrived tax avoidance.
