The hearings of the Public Accounts Committee come as two reviews of the States’ policy on travel and accommodation, including what has been spent by civil servants and politicians since January 2013, are continuing.

Those reviews, the results of which are due to be published by the end of next month, were launched after this newspaper revealed that Economic Development chief executive Mike King and Locate Jersey’s Wayne Gallichan had spent almost £13,000 of taxpayers’ money on fully flexible business-class tickets to South Africa to attend a mining conference.

A disciplinary investigation is also under way.
