Mehghwal had been eyeing a ticket to contest the Shahpura Assembly segment and announced himself as an Independent candidate for the seat after he failed to secure a saffron ticket.
The BJP, earlier, fielded Lalaram Bairwa as its Assembly poll candidate from the Shahpura constituency.
Earlier, the BJP's state unit had similarly expelled the former state president of the party's Scheduled Tribe Morcha Jitendra Meena for contesting the upcoming state election from the Bassi constituency against the officially declared candidate of the party.
"You are contesting the Bharatiya Janata Party Rajasthan Assembly Elections 2023, being the primary member of BJP, against the officially declared candidate of Bassi region. Thus, you are guilty of breach of discipline mentioned in Section 25 (9) of the Constitution of the Bharatiya Janata Party. Therefore, the State President of Bharatiya Janata Party Rajasthan has decided to immediately expel you from the primary membership of BJP," read the letter addressed to Jitendra Meena undersigned by Onkar Singh Lakhawat.
Meanwhile, Prime Minister Narendra Modi as part of BJP's election campaign will again visit poll-bound Rajasthan this week, with a huge rally in Barmer on Wednesday, and Bharatpur and Nagaur later on Saturday.
Rajasthan will go to polls on November 25 and the counting of votes will take place on December 3.
In the 2018 Assembly elections, the Congress won 99 seats while the BJP finished a close second at 73 seats in the 200-member House.
Congress formed the government with support from the BSP and Independents.
