Vince Cable, a former business secretary, has called for an investigation into the time Andrew Mountbatten-Windsor served as a trade envoy.
Mr. Cable believes this period should be examined for possible acts of corruption. MyJoyOnline reported on his statements.
The role of a trade envoy involves promoting business and investment between countries. It is a position of public trust.
An investigation would seek to find out if any rules were broken or if any improper actions occurred.
The call for a probe indicates serious concerns about the integrity of the trade envoy's activities.
Such investigations help ensure that public officials act honestly and in the best interest of the nation.
