Text of Mr Speaker Bercow's statement on the searching of an MP's office yesterday:
I should remind Members, as did my predecessor in 2008, that the precincts of Parliament are not a haven from the law. In accordance with the Protocol issued by my predecessor on 8 December 2008 on the execution of search warrants within the precincts of the House of Commons, I considered the warrant personally and was advised by Officers of the House that there were no lawful grounds on which it would be proper to refuse its execution.
In addition, as provided for in paragraph 6 of the Protocol, I consulted the Attorney General and the Solicitor General who concurred in this advice. I am very grateful to them. The Clerk of the House was kept fully informed throughout, and also concurred.
The Serjeant at Arms and Speaker’s Counsel were present when the search was conducted. Undertakings have been given by the police officers as to the handling of any Parliamentary material until such time as any issue of privilege is resolved.
The investigation is continuing and it would not be right to comment further. I will not take questions on my statement."
Lancashire Police have confirmed they have searched "offices in London" after going through appropriate procedures.
