Not sure what "socialism" has to do with it? This is about MP's expenses. In this article the Mirror says that Bryant claimed £3600 + £6400 + £1000 + £42,500 + £84,300 over 14 years (although it was probably less as they double counted 2004 and guesstimated the £1000)
Even if the Mirror's figures are accurate that makes a total claim of £134K aka £9585 per annum average.
And when the rules changed on MPs expenses in 2014 Bryant stopped claiming for his property.
Compare that to leading Brexiteer Tory Trade Secretary Liam Fox who has claimed over £150k since 2012
And Michael Gove who sold the house he had been claiming on for over a million!
Now obviously profiting from these sales of "second London homes" does eventually benefit the public purse as at London prices they will have to pay 40% tax and will in most cases return more to the public purse than the amount they were subsidised.
But it doesn't change the fact that of the 160 MPs who claimed over many, many years (which is how the Mirror managed to inflate this into a story) profits on the sale of second London homes averaged £193,000 for Labour MPs and a whopping £417,000 for Tory MPs.
So explain to me WTF this has to do with socialism?
