The Election Commission has called the income tax department chief and the revenue secretary today to discuss tax raids across the country, just days before the national elections starting Thursday. The opposition has alleged the Prime Minister Narendra Modi government is using the tax department to harass and intimidate them before the elections, after a string of raids on people linked to opposition leaders - Bahujan Samaj Party chief Mayawati, Karnataka Chief Minister HD Kumaraswamy and Madhya Pradesh Chief Minister Kamal Nath - raised their suspicion.
