The Rajasthan Governor must call an assembly session to let the Congress prove its majority, party leader Rahul Gandhi on Friday said, alleging that the BJP's conspiracy to topple the Ashok Gehlot government was now clear. "The country is ruled in accordance with the law and constitution. Governments are formed and run based on people's mandate. BJP's conspiracy to topple the Rajasthan government is clear. This is an insult to 8 crore people of Rajasthan. The governor must call assembly session so that the truth comes before the country," Mr Gandhi tweeted in Hindi.
