The Election Commission (EC) faces a unique challenge as a record number of 18 Bharatiya Janata Party (BJP) MPs are contesting assembly elections in five states, with more expected to join. This could result in a significant number of bypolls within six months of the elections. The Constitution states that a person cannot be a member of both Parliament and a State Legislature, so sitting MPs who win assembly seats will have to decide which seat to retain, potentially leading to bypolls.
