Senior Aam Aadmi Party leader Manish Sisodia on Wednesday thanked the people of Delhi for voting his party to victory in the Municipal Corporation of Delhi polls and said it was their mandate that helped it defeat the "world's biggest and most negative party".

Of the 250 wards under the MCD, the AAP crossed the majority mark of 126. The BJP, which exit polls predicted would suffer a massive defeat, put up a spirited fight.

"Heartfelt gratitude to the people of Delhi for trusting Aam Aadmi Party in Delhi MCD. By defeating the world's biggest and most negative party, the people of Delhi have made a hardcore honest and working @ArvindKejriwalji win," Sisodia said in a tweet in Hindi, targeting the BJP.

"For us, this is not just a victory, it is a big responsibility," he said.

The high-stakes election was held on December 4, sealing the electoral fate of 1,349 candidates in voting machines.

A voter turnout of 50.48 per cent was registered in the elections.

The results of this election may have ramifications beyond the national capital.
