Lord Evans of Watford says he referred himself to standards commissioner after Guardian undercover filming

Lord Evans of Watford, the Labour peer facing cash-for-access questions, is under formal investigation by the Lords standards watchdog after undercover filming by the Guardian.

The Lords commissioners for standards announced on Tuesday that David Evans, 82, was under investigation for potential breaches of the House of Lords rules, including a requirement for peers to “act always on their personal honour” as parliamentarians.
