Re-polling has begun in six booths of Tripura Assembly constituencies on Monday. The Election Commision (EC) had ordered the fresh voting in - Dhanpur, Sonamura, Teliamura, Kadamtala-Kurti, Ampinagar and Sabroom Assembly constituencies due to criticism from the ruling Communist Party of India (Marxist) CPI(M), which accused the Tripura election department of failing to carry out a proper election.
