Recall of MPs Bill

Before my noble friend concludes his remarks, would he do us the courtesy of dealing with the argument about 10 and 20 days? I listened very carefully to what he said and the only justification he put forward was that this was passed by the House of Commons. There have been a number of speeches making very pertinent points about ensuring that there is public confidence in parliamentary procedures. Will the Minister explain why the Government are rejecting those arguments?
