The Metropolitan Police has issued an apology to Commons Speaker Sir Lindsay Hoyle after disclosing that he was the source of information that led to Lord Mandelson's arrest earlier this week.

Lord Mandelson was arrested at his home on Monday afternoon following a tip-off from Sir Lindsay, who believed the information he possessed was relevant to an ongoing investigation. The Commons Speaker told MPs he had acted "in good faith as is my duty and responsibility" when he passed the information to Scotland Yard.

The arrest prompted significant attention, with the incident described as dramatic by those familiar with the circumstances. However, the subsequent revelation that Sir Lindsay was the source of the tip-off appears to have created complications that led to the police apology.

Sir Lindsay defended his actions to Members of Parliament, emphasizing that he felt obligated to share what he considered relevant information with the authorities. The Speaker's role traditionally involves maintaining the integrity and security of parliamentary proceedings, which may have influenced his decision to contact police.

The Metropolitan Police's apology suggests there may have been procedural issues with how the source of the tip-off was handled or disclosed. The incident highlights the delicate balance between parliamentary privilege and cooperation with law enforcement investigations.

Further details about the nature of the investigation or the specific circumstances surrounding Lord Mandelson's arrest have not been publicly disclosed.
