This figure looks bad until you calculate what the total salary bill is for 650 MPs at that rate for the three years covered, and work out that 17 million is just 10% of the total salaries.
And then you read on and realise that actually _most_ MPs can't possible be in on this, it's a small group making out like bandits. Absolutely get those people.
That's diarrhoea.
Diaeresis is the non-linear behaviour of a system in which the history and previous states of the system affect current responses to inputs.
