The Business Secretary will unveil details today of a crackdown on excessive boardroom pay.
Vince Cable will publish plans to make remuneration more transparent and to hold boards more accountable for pay packages handed out to senior executives.
It follows the cases of firms like WPP whose shareholders voted against a huge pay increase for Chief Executive Martin Sorrell, but were ignored.
However, it is reported Vince Cable may have trouble pushing through the more contentious reforms.
- He is said to be watering down aims to introduce a binding vote on pay, by requiring an investor poll every three years rather than annually, unless a company changes a director's deal
- He will have to consult further on one of the key aims in the clampdown - to force companies to reveal a single figure for each director's remuneration
Recently government sources told our Business Editor Laura Kuenssberg that any new rules would not bind firms like WPP by law. They are one of a group of companies who are listed on the FTSE 100 but incorporated somewhere else.
At the moment they choose to follow the UK standards and conventions and have advisory votes. But the government does not believe they could be compelled to have legally binding votes, whether every year or every 3 years, when the law changes.
Last week, WPP shareholders voted against the company's executive pay report by a majority of 59.5%.
Last month, shareholders in the insurance company Aviva voted down its remuneration report.
And before that, Barclays, one of the most powerful institutions in the world also faced a revolt from its shareholders.
