Bihar Election Result 2025: In the 2025 Bihar Assembly election results, NDA achieved a strong victory by crossing the 200 seats mark. On the other hand, the presence of the Grand Alliance was limited to only 35 seats. Meanwhile, an important question is being raised in political discussions that how many seats any party has to win to get the post of leader of the opposition. Let us know.
10% rule
The post of Leader of Opposition does not automatically go to the largest opposition party. Actually it is governed by a rule. To officially get this constitutional post, it is necessary for any party to get at least 10% of the total strength of the House. This rule applies only to a single party and not to any alliance. If we talk about Bihar’s 243-member assembly, then a party will have to win at least 25 seats. If no party meets this threshold, the House functions without an officially recognized Leader of the Opposition.
Why is this rule necessary
This 10% rule is necessary because the post of Leader of Opposition holds considerable political importance. This prevents very small parties from claiming positions designed to balance the ruling government. In fact, a recognized opposition leader has a lot of institutional importance. This rule ensures that this responsibility rests with the party that has the most important mandate.
How does this rule apply in all legislatures?
If we talk about Lok Sabha, any party should have at least 55 seats to get the status of Leader of Opposition. On the other hand, based on the total number of seats in Rajya Sabha, the required number is approximately 25 seats.
role of leader of opposition
Being a leader of opposition is a big responsibility. It strengthens democratic accountability. The Leader of the Opposition participates in major selection committees for top national institutions. These include the appointment of Director of Central Bureau of Investigation, Chief of Central Vigilance Commission, Chairman of National Human Rights Commission and Lokpal.
