Antony Sumara spoke to the BBC's health correspondent in the West Midlands, Michele Paduano.
The Stafford Hospital Public Inquiry, which was called after a higher than expected number of deaths at the hospital, has been told a similar situation could reoccur.
The present chief executive of the trust that runs Stafford Hospital said he had no confidence regulators would be able to prevent a similar situation arising. Antony Sumara said he thought the regulation system needed overhauling.
The BBC's health correspondent in the West Midlands, Michele Paduano, was at the inquiry.
