"It is the people's recognition to the development activities of the UDF government", he told reporters here after the announcement of results.
By this win, UDF has overcome all the 'baseless allegations' raised by LDF and also the challenge posed by the Sangh parivar, he added.
From the start of the poll campaign UDF parties had put up a united show unlike LDF leaders, who could not be seen on the same platform, Veerendrakumar said.
In a triangular contest, Sabarinadhan polled 56,448 votes against former speaker Vijayakumar who came second with 46,320 votes. BJP candidate and former Union Minister O Rajagopal gained 34,145 votes in his favour.
Veerendrakumar urged the secular and democratic parties, including the Left, to unitedly contest the coming assembly polls in Bihar so that anti-BJP votes would not split.
"Now the party is a part of UDF," he said to a question about his party's stand on alliance in the state.
