It is known that elected representatives step down when gross/complete failure of their responsibility occurs. Like owning up responsibility in accidents caused by negligence.That is in proper spirit.
However has there been at any time in democratic history an elected representative or a group/party stepping down after non-completion of works/tasks promised in the manifesto ahead of his term of office? Of course it would be a disadvantageous gullible act of idealism on part of the legislator.
Can such a provision ( continuation of office linked to MP's performance ) ever be built into the Constitution a priori in order to exercise a powerful control by the people/electorate to check on non-performing electees?
The question arises with voters who have waited for too long with frustration as representatives do not deliver what is expected of them in time ... thereby failing to discharge accepted manifesto commitments.
EDIT:
Any service ordered on taxpayers' money by government, on itself or another service handler, should be actually performed. Else it tantamounts to giving out free holidays.
Why does not government act to assess legislative services received in return ( when not returned in adequate measure) to take remedial measures?
Why should the electorate be indifferent to such a crucial legislative deficit in execution? i.e., executive deficit in legislation?
