Lord Steel suggests this would be "simple, inexpensive and likely to produce a less London-centric chamber than at present", adding "such a fundamental, democratically reformed upper chamber would maintain the existing revising role, be part-time and unpaid, though needing tougher declaration of interest rules than at present". The Senate would retain existing powers and conventions. It follows that, after each General Election, the new cohort of 150 senators would have a similar party make-up to the Commons, whilst the other 300 senators would continue in post, unaffected by contemporary electoral swings.
