If MPs had any sense of firm and clear leadership, they would have frozen their own pay and cut their allowances before insisting on the same from other public servants.
That they did no such thing and are now seeking to increase their own pay says it all.
As a case in point, I am about to take up a public service post and have asked for a salary significantly below the average for the post. The money thus saved will be distributed amongst the salaries of the other staff. And yes, if anyone asks, I do intend to embarrass the heck out of the other money grabbers.
