The Congress today won crucial by-elections in two assembly seats in Madhya Pradesh, seen as a semi-final before assembly elections later this year. The Congress held both seats - Mungaoli and Kolaras - which were vacated by the death of its sitting legislators. The ruling BJP had gone flat out to try and wrest the seats away from the opposition party with Chief Minister Shivraj Singh Chouhan leading an aggressive campaign. In the Bijepur assembly by-election in Odisha, the ruling BJD won the seat that was held earlier by the Congress.
