The simple answer is that if Congress party asks Mrs. Pratibha Patil or Mr. Hamid Ansari to resign after Congress losses the next election - they should resign as Indian Politics is based on Party system from UK and not like the US - Presidential system. In India, the party can ask a member to resign because the member got elected to the august body of parliament on that Party's Ticket and not as an individual. Mr. Somnath Chatterjee was first an MP elected on the Left Party's ticket after which he became speaker - therefore if the Party asks him to resign he has to resign and if he does not he can be expelled from the party.
