Lucknow: The AAP logo's designer who has quit the party has served a legal notice to Delhi Chief Minister Arvind Kejriwal for still using the logo for which he holds the copyright.

Sunil Lal told IANS that he had served the notice through his lawyer Akhilesh Chandra seeking a response within 15 days for continuing to use the logo. Lal has severed ties with the Aam Aadmi Party.

"I designed the logo, given it to the party but withdrew it after my belief in the party and its ideology was shattered," Lal said, adding he wrote a letter to Kejriwal on April 7 seeking the logo back.

"I had categorically requested the AAP not to use the logo designed by me in posters, banners, flags, websites and other means of publicity. But they continue to use it blatantly," he said.

He said the logo was his intellectual property that was never transferred to the party.
