"The second homes allowance claims included £30,525 on food between 2004 and 2008, with the couple claiming the maximum £400 per month each in most months".
This is despite the fact that the since 2005 Peter Robinson has been present for only 37.4% of parliamentary votes and Iris for only 28.4%. So - on top of the £571,939 tax-payer funded salaries of the Robinson family - Peter and Iris claimed the maximum food allowance while being present in Parliament for only 1/3rd of the time.
By the way, the average UK family food bill is calculated to be £100 per week for a family of four, equating to £5,200 per year. Peter and Iris' average yearly food bill for part-time parliamentary attendance - 2/3 days a week at most - is a whopping £6,105.
