Jo Johnson calls for 'restraint' in university pay
Universities in England could face fines if they pay their leaders more than the prime minister - unless they can convince a regulator that their bosses are worth it.
Dozens of vice-chancellors currently earn more than double the prime minister's annual salary of £150,000.
In a speech to university leaders, Universities Minister Jo Johnson said tertiary education should be a good deal for both students and taxpayers.
