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..
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.
