In India, one of the common threads that run through many of the corruption scandals is the issue of conflict of interest i.e. public officials taking policy decisions based on their personal interest.  For example, Shashi Tharoor in the IPL controversy or Ashok Chavan in the Adarsh Housing Society scam. Many countries take measures to minimize conflict of interest of its MPs by regulating membership of parliamentarians in Committees, making it mandatory for them to declare pecuniary interest, and restricting employment both during and after completion of tenure.  For example, the US Senate has a detailed Code of Official Conduct that provides guidelines on conflict of interest. India also has some measures in place to minimize conflict of interest.  These are codified in the Code of Conduct for Ministers, Code of Conduct for Members of the Rajya Sabha, Rules of Procedure and Conduct of Business in the Lok Sabha and Rajya Sabha and Handbook for Members of Lok Sabha and Rajya Sabha.  Every Rajya Sabha MP has to declare his or her interest (along with assets and liabilities).  He has to declare five pecuniary interests:  remunerative directorship, remunerated activity, majority shareholding, paid consultancy and professional engagement.  Lok Sabha MPs can object to another MP joining a parliamentary committee on grounds that he has personal, pecuniary or direct interest.  (For more details, see PRS note on Conflict of Interest Issues in Parliament). On December 1, 2010, PRS held its annual Conference on Effective Legislatures.  One of the topics discussed was MPs and Conflict of Interest: Issues and Resolution.  Panelists included D Raja, Prakash Javdekar and Supriya Sule.  Issues such as requirement for transparency, expertise of legislators, election of honest legislators, and ethical media were discussed.  The issues that were raised during the discussion are summarised in the PRS Summary of Proceedings from the Conference.

We wrote an FAQ on Parliamentary Privilege for IBN Live. See http://ibnlive.in.com/news/what-puri-bedi-are-guilty-of-parl-privilege-faqs/179977-37.html The full text is reproduced below. Several MPs have given breach of privilege notices against actor Om Puri and ex-policewoman Kiran Bedi for using "derogatory and defamatory" language against Members of Parliament. In light of this, we explain the concept of breach of privilege and contempt of Parliament. What is parliamentary privilege? Parliamentary privilege refers to rights and immunities enjoyed by Parliament as an institution and MPs in their individual capacity, without which they cannot discharge their functions as entrusted upon them by the Constitution. Are these parliamentary privileges defined under law? According to the Constitution, the powers, privileges and immunities of Parliament and MP's are to be defined by Parliament. No law has so far been enacted in this respect. In the absence of any such law, it continues to be governed by British Parliamentary conventions. What is breach of privilege? A breach of privilege is a violation of any of the privileges of MPs/Parliament. Among other things, any action 'casting reflections' on MPs, parliament or its committees; could be considered breach of privilege. This may include publishing of news items, editorials or statements made in newspaper/magazine/TV interviews or in public speeches. Have there been earlier cases of breach of privilege? There have been several such cases. In 1967, two people were held to be in contempt of Rajya Sabha, for having thrown leaflets from the visitors' gallery. In 1983, one person was held in breach for shouting slogans and throwing chappals from the visitors' gallery. What is the punishment in case of breach of privilege or contempt of the House? The house can ensure attendance of the offending person. The person can be given a warning and let go or be sent to prison as the case may be. In the case of throwing leaflets and chappal, the offending individuals were sentenced to simple imprisonment. In the 2007 case of breach of privilege against Ambassador Ronen Sen, the Lok Sabha Committee on privileges held that the phrase "headless chicken" was not used by Shri Sen in respect of MPs or politicians. No action was taken against him. In 2008, an editor of an Urdu weekly referred to the deputy chairman of Rajya Sabha as a "coward" attributing motives to a decision taken by him. The privileges committee held the editor guilty of breach of privilege. The committee instead of recommending punishment stated that, “it would be better if the House saves its own dignity by not giving undue importance to such irresponsible articles published with the sole intention of gaining cheap publicity.”
