The figure, in the latest pay report by proxy voting agency Manifest and remuneration consultancy MM&K, has reignited the row over executive pay which has recently been played out in the so-called Shareholder Spring.

He said: "What has emerged in recent years is that executive pay has gone way ahead of the performance of companies and that's why we've seen this rebellion by shareholders."
