New Delhi: The counting of votes for by-election in 11 constituencies in eight states began at 8 am this morning and most of the results for eight of the ten constituencies have been declared. The BJP has won five of the ten constituencies so far - with results for two yet to be declared. The Congress has retained both the seats it had in Karnataka, while the Trinamool Congress won the seat in Bengal. The Aam Aadmi Party, however, faced a big loss in Delhi. It even had to forfeit it's deposit. The BJP has won Delhi's Rajouri Garden by a margin of over 14,000 votes against the Congress, which came second. This increases their tally in the Delhi Assembly to 4. The win in Delhi will be seen as a crucial one for BJP ahead of the high-stake civic body elections scheduled for April 23. The BJP won in Delhi, Himachal Pradesh, Assam, Rajasthan and Madhya Pradesh. The Congress has won both constituencies in Karnataka. Counting of votes is currently under way for the second constituency in Madhya Pradesh and one in Jharkhand.
