Mzzz Beria had reported to Parliamentary authorities that the house in her constituency she shares with her husband and children was her second home, which allowed her to claim the money - paid tax-free - from the Additional Costs Allowance pool.
However, speaking to journalists yesterday while writhing scantily-clad on a bed strewn with £50 notes, Mzzz Beria admitted that the claim was 'an error of judgement' that she would be rectifying in future.
She added, "I've made such a cock-up. It turns out I could have been claiming £24,000 per year and I've only actually been claiming £22,000. It's so embarrassing. I will, of course, be making a full apology to the House for failing fully to dig my Stalinist snout into the trough".
Mzz Beria defended classing her family home as the second home, saying, "it's perfectly legitimate and right to do so, as it allows full exploitation of the expenses system. And anyway, who would want to admit to living in Redditch?"
The Home Secretary earns a Ministerial salary of £142,000 and claimed a further £152,000 in expenses in the '06-'07 financial year - including £40,000 paid to her husband who is apparently her assistant, despite living almost 120 miles away from her day-to-day office.
