We discovered Mr Agyemang-Prempeh had then begun offering CoS for UK jobs in construction - another industry that allows employers to recruit foreign workers. He was able to set up his own construction company and obtain a sponsorship licence from the Home Office.

Our journalist, posing as a UK-based Ugandan businessman wanting to bring Ugandan construction workers over to join him, asked Mr Agyemang-Prempeh if this was possible.

He replied it was - for the price of £42,000 ($54,000) for three people.

Mr Agyemang-Prempeh told us he had moved into construction because rules are being "tightened" in the care sector - and claimed agents were eyeing other industries.

"People are now diverting to IT," Mr Agyemang-Prempeh told the undercover journalist.
