LONDON - An Extraordinary details of criminality within the British Parliament have been uncovered by a recent investigation, according to a report. The 'Mother of Parliaments has played host to offences ranging from the serious to the ridiculous, including death threats, confiscated weapons and stolen bottles of whisky. MPs, peers and former Commons Speaker Michael Martin were all victims, according to unpublished documents from Scotland Yard obtained by the Evening Standard under freedom of information laws. The most common offence was theft. One 25 (Rs 2700) orchid was stolen from the Westminster sports club, used widely by politicians, officials and journalists, while a 100 (Rs 13500) satellite navigation was taken from a security guards hut next to Downing Street. A security officer suffered a racial assault behind the Speakers chair in the Commons, regarded by insiders as the inner sanctum of British democracy. The documents reveal more than 1,000 visitors with criminal records gained access to the parliamentary estate, while hard-pressed detectives had to respond to more than 2,600 requests to unlock doors. It follows the expenses scandal, which has seen MPs and a peer convicted over false claims. Documents obtained from SO17 - a Scotland Yard unit struggling to uphold the rule of law within Parliament - reveal officers also dealt with a stolen 1,000 (Rs 1,35,000) candlestick and harassment of MP. A 25 (Rs 3000) bottle of whisky was stolen from a peer in the House of Lords. The number of offences recorded by SO17 more than tripled in two years, from nine in 2007 to 28 in 2009, the latest year with full figures. SO17 is a little publicised unit of Scotland Yard officers that guard the Palace of Westminster. Besides the Commons and Lords, the Palace covers buildings connected to the main site by underground passages, including Downing Street and Portcullis House. Last July an MP received a death threat. In 2008 detectives responded to three bomb hoaxes. In June that year, someone was arrested trying to enter Parliament with an offensive weapon. Days before he stepped down as Speaker in June 2009, Michael Martins office received a malicious communication which was referred to Scotland Yard. And a person was arrested for using a false ID card to try to enter the office of Black Rod, a senior Commons official. One Minister suffered the theft of a laptop worth 1,115 (Rs 1,55,000) from a corridor near the Commons, while last July, computers worth 6,000 (Rs 7,80,000) were stolen from Millbank, the Westminster studio for TV and radio crews. In October 2008, detectives arrested two individuals making off with 10 500 (Rs 65,000) chairs from Portcullis House, an administrative complex. The 100 sat-nav was stolen from a security officers mess near the Prime Ministers house in Downing Street. Last February, an unknown figure was arrested at the Cromwell Green entrance in possession of hashish. Tantalisingly, it was the only crime where police failed to record if the offender was a politician or member of the public.Victims identities are almost never revealed in the documents. However, the Standard has established MP Andrew MacKay, the former aide to David Cameron who resigned over his expenses, suffered a theft when golf clubs worth 1,500 were taken from his BMW in the Commons car park in May 2008.
