The two ministers, who were inducted in the Union Cabinet on October 27, are not members of the Parliament and required to be an MP within six months of being a minister.
Prabhu, a former Shiv Sena leader, quit the party to join BJP just before being sworn in as Railway Minister, while Singh was earlier a Rajya Sabha member of Congress from Haryana but quit his seat to join the saffron outfit ahead of the October 15 assembly elections in the state.
Today was the last day of filing of nominations for the by-elections. With no paper being filed by any other candidate, both Prabhu and Singh are all set to enter the Upper House uncontested. In the 90-member Assembly, BJP has 47 MLAs and it also enjoys support of five more legislators including the lone BSP member.
Singh, who as Congress Rajya Sabha member, had last year made a sensational claim that berths in the Upper House were available for Rs 100 crore, today joked when asked if he had paid any amount now, saying "apna to sau rupyein mein kaam chal gaya (my job was done in just Rs 100)".
The scrutiny of nominations will take place on November 26 and the last date of withdrawal is November 28.
The by-elections were necessitated as the seats had fallen vacant after Birender Singh resigned from his seat on August 28 and Ranbir Singh of Indian National Lok Dal (INLD) quit on November 1 after being elected to the assembly from Nalwa seat.
