Mirdha entered active politics in 1953 after resigning from the
Rajasthan Administrative Service. He was elected in a by-election from the
Jayal constituency of
Nagaur district to the
Rajasthan Legislative Assembly the same year. He was re-elected in 1957 and 1962, and from 1957 to 1967 he served as the
Speaker of the Rajasthan Legislative Assembly, becoming its longest-serving presiding speaker to date. During this period, he also handled ministerial responsibilities in the
Government of Rajasthan, including portfolios such as Agriculture, Irrigation, and Transport. In 1967, Mirdha was elected to the Rajya Sabha, where he served for multiple terms until 1984. In 1973, following the death of Chief Minister
Barkatullah Khan, Mirdha was considered a leading contender for the chief ministership of Rajasthan and reportedly enjoyed the backing of Prime Minister
Indira Gandhi. However, he lost the Congress Legislature Party vote to
Hari Dev Joshi, which prevented him from becoming the first Jat
chief minister of Rajasthan. He held several responsibilities in the upper house, including
Deputy Chairman of the Rajya Sabha from 1977 to 1980. During this tenure in the
Rajya Sabha, he was appointed Minister of State in various departments under Prime Minister
Indira Gandhi, including
Home Affairs,
Defence, and
Personnel, Public Grievances and Pensions during the 1970s. In 1983, Mirdha was elevated to the Union Cabinet as
Minister of Irrigation. Following the general election of 1984, he was elected to the
Lok Sabha from
Nagaur, defeating his uncle
Nathu Ram Mirdha. In the
Rajiv Gandhi ministry, he served as Minister of State for
External Affairs (1984), Cabinet Minister for
Communications (1985–1986),
Textiles (1986-1989),
Health (1989), and Water Resources (1987-1988).
Joint Parliamentary Committees Mirdha played a role in parliamentary committee work, most notably as Chairman of the
Joint Parliamentary Committee (JPC) on Irregularities in Securities and Banking Transactions (1992–93), which was constituted following the 1992
Harshad Mehta securities scam. The committee examined irregularities in banking operations and the securities market, the involvement of brokers and financial institutions, and regulatory lapses that allowed the scam to occur. == Public image ==
