New Delhi, Aug.21 The Congress and its allies on Friday won nine of the 17 seats in assembly by-polls spread over five states.

In Tamil Nadu, the win for the Congress and its ally the DMK was largely helped by the boycott of opposition AIADMK and its partners.

The DMK bagged three seats-Cumbum, Burgur and Ilayankudi. The remaining two seats Srivaikuntam and Thondamuthur went to the Congress. DMK President and Chief Minister M Karunanidhi attributed the performance to achievements of the UPA Government and his government in the state.

In Chitapur, Priyanka Kharge, son of Union Labour Minister M Mallikarjun Kharge, lost to the BJP's Valmiki Nayak.

The Janata Dal-Secular won two seats retaining Ramnagara and Chennapatna. The BJP bagged Chitapur and Kollegal.
