Delhi Congress' interim chief Devender Yadav on Saturday described former party unit president Arvinder Singh Lovely, who joined the BJP, as an "opportunist".
"The Congress does not care about such people. It was strong before and will remain strong in the future," he said.
It is believed that he and some other leaders were also upset with the Congress' choice of candidates, including Kanhaiya Kumar and Udit Raj, in the national capital for the Lok Sabha elections.
Reacting to Lovely joining the BJP, Yadav said, "I put Arvinder Singh Lovely in the category of an opportunist person. This is not the first time that he has tried to sabotage the Congress."
"The party does not care much about such people. The Congress was strong before and will remain strong in the future as well. This is their habit. Whenever there is a chance, he (Lovely) has tried to cheat and there is no place for cheaters in the party," he added.
This will be Lovely's second innings in the BJP after he left it to rejoin the Congress in 2018 following a brief stint in the saffron party.
