Haryana MLA Kuldeep Bishnoi, who was expelled by the Congress from all party positions for cross-voting in the June Rajya Sabha polls, resigned from the assembly Wednesday, a day before he joins the ruling BJP.
The 53-year-old Mr. Bishnoi submitted his resignation to Speaker Gian Chand Gupta here.
This necessitates a bypoll for the Adampur seat in Hisar district, which Mr. Bishnoi currently represents.
