Singh also extended his best wishes to Kejriwal's six Cabinet ministers who were also sworn in with him.

"I am congratulating Kejriwal on becoming the chief minister of Delhi and conveying my best wishes to him," he said in a statement.

"I also extend my wishes to his cabinet members," he added.

45-year-old activist-turned-politician Kejriwal on Saturday took oath as Delhi CM at the sprawling Ramlila Maidan along with six cabinet ministers.

His party won only 28 seats in the 70-member Assembly, and will be dependent on the legislative backing of the eight legislators of the Congress, which was voted out after 15 years.
