This is the point lost in all of the shouting from opponents of the pay rise. IPSA has said it will not cost taxpayers a penny more. If you don't pay MPs a decent salary, then you don't get the best people applying for the job. Peanuts and monkeys.
HOWEVER, we do not need 650 MPs to represent 63.5 million people. Cull the number of MPs by reducing the total by one third and you've got yourself a decent cost saving.
Depends what you mean by best. Best to me is a government representative of the people it works for. All you need is someone who understands and is reasonably smart.
