Embezzlement rewarded

Let's see if I have this right. Tory MP Derek Conway used his parliamentary expenses to fund his son's party life-style. The Conway brat was given £45,000 over two-and-a-half years while "studying" full-time at Newcastle University (and it seems a second son has also been recieving wads of cash). Now the House of Commons has ordered the MP to pay back £13,161. So, if I steal £45,000 of taxpayers money and get caught, will I only have to pay back 29% of it? Come to think of it, if I stole £45,000 I rather think I would now be sitting in a police cell.
