The nature in which WPP chief executive Sir Martin Sorrell Has stood down after 33 years, where he became the longest-serving and highest paid boss of a FTSE 100 company, is a big issue.

He said it was in “the best interests of the business” for him to resign following an investigation into wrong-doing, that he denied.

The case reinforces the point that no matter how successful they are, executives are managers of companies- answerable to shareholders and other stakeholders at all times.

When they deviate from that idea, they should not be in place a moment longer.
