Appalling
No person connected with another nation, this by virtue of citizenship or employment, should be a member of the final decision-taking panel. Similarly, wholly British controlled commerce should be kept at arms length from the panel.
That's not to say experienced people in relevant business sectors shouldn't be consulted on aspects of the job description, on desirable skills and experience, and on work priorities to be listed in the job description. Maybe, pre-final interview the candidates could go before panels of businessmen and high ranking IT people; their purpose would be to identify aspects of apparent strength or weakness in candidates to be formulated as candidate specific areas for questioning in depth. This need not go against the broad principle of subjecting all candidates to all relevant topic areas.
The present government has already been flagged for enquiry about aspects of financial probity. It should heed warning that scrutiny cannot be avoided.
