The prime minister has repeatedly said he does not favour a so-called "in-out" referendum on the UK's membership of the EU, in which people would be asked whether they wanted to stay in the organisation or to leave.
Nearly two thirds of voters plan to back the so-called anti-fat cat initiative in the referendum that would allow a binding annual shareholder vote on executive compensation for listed companies and block big payouts for new hires and for managers when they leave.
However, many Conservatives have been pressuring the government to commit to a referendum on the question of whether the UK remains in the EU - a so-called "in-out vote".
