The new head of Alberta's super health council was once involved in a private clinic proposal in Mexico.

The Opposition Liberals have released documents showing that 10 years ago, Ken Hughes was involved in the proposal to build a private hospital in Los Cabos.

Liberal health critic Dave Taylor says this suggests Hughes, who is interim chairman of the new Alberta Health Services Board, is a fan of private, for-profit health care.

But Hughes says he acted only as a consultant to a group exploring the idea of setting up an emergency clinic in Mexico and the proposal was later dropped.

Hughes, who runs a private insurance brokerage, says he's committed to building a health-care delivery service that falls within the Canada Health Act.

Health Minister Ron Liepert says Hughes is a respected businessman and it's shameful for the opposition to paint him as someone bent on privatizing health care in Alberta.
