LONDON (AFP) - British lawmakers were ordered Thursday to repay more than one million pounds of expenses, after an investigation into a scandal, which rocked parliament slammed a deeply flawed system. The long-awaited audit by former civil servant Thomas Legg said lawmakers must return 1.1 million pounds in payments received for loans on second homes, gardening and cleaning expenses. Legg found that more than half of all members of parliament (MPs) made inappropriate or excessive claims. The scandal reached a peak last year when one MP for the main opposition Conservatives, Peter Viggers, was found to have claimed more than 1,600 pounds for a duck house to stand in a garden pond. It was revealed Thursday that Viggers must repay a total of 13,245 pounds. But the largest repayment was 42,458 pounds from Barbara Follett, an MP from the ruling Labour party who is married to best-selling novelist Ken Follett. Most of the money was spent on security patrols at the Folletts second home, as well as more than 4,500 pounds for what the audit said was an excessive six telephone lines at the property. Follett, a minister with responsibility for local government, said she had repaid the entire sum, but argued she had claimed the amounts in good faith in accordance with the rules at the time. This has been a sad and sorry episode in Britains political life which I deeply regret, she added. Many other MPs are unhappy at the investigation, arguing that Legg has effectively imposed retrospective rules and spending limits. But he rejected the criticism, saying the system had been deeply flawed and open to abuse and MPs had encouraged a culture of deference from parliamentary officials who were meant to scrutinise the claims. Legg insisted the regulations on second home allowances stipulated that they could only be used as reimbursement for specific and proportionate expenditure on accommodation needed for the performance of parliamentary duties. In a scathing assessment, Legg said that between 2004 and 2009, senior figures in parliament had been more focused on furthering the immediate interests of MPs than propriety in public expenditure. The row over expenses erupted in May when The Daily Telegraph newspaper published leaked details of thousands of claims, for everything from flat-screen TVs to massage chairs. The scandal led to an overhaul of the expenses system, but not before dozens of MPs promised to stand down at a general election due by June, and a number resigned, including the speaker of parliaments lower House of Commons. Gordon Browns spokesman said the prime minister, who himself was earlier asked to repay 12,888 pounds for cleaning, decoration and gardening services, regarded Leggs report as a very significant step forward. The PM said from the outset that this was a very important inquiry, that he fully supported the approach and he encouraged MPs to pay back as he did as quickly as possible, the spokesman said.
