Forty members of the House of Lords have been reported to parliamentary authorities, in what is believed to be one of the most wide-scale breaches of transparency rules ever reported in Westminster.
The news comes after openDemocracy revealed how dozens of Lords appear to have flouted rules by not declaring details of private companies they run.
Rules say that if a lord is a company director, they should “give a broad indication of the company’s business, where this is not self-evident from its name”. But openDemocracy found that dozens of peers have not done this.
