AAP

The city, a federally-administered territory, has been governed by the AAP since 2013, with voters backing its strong record of welfarism.

The party governed Delhi from 1998 to 2013, but was ousted over allegations of corruption that saw voters turn to AAP instead.

The AAP and BJP campaigns both promised improvements to public schools and free healthcare services as well as cash handouts to women.

It would also be a big blow to the AAP, a much smaller party which was praised in its early years in power for focusing on improving education and health facilities in the city.

Much of the BJP campaign targeted the AAP's chief Arvind Kejriwal, an anti-graft activist, who was jailed in a corruption case relating to a now-scrapped alcohol sales policy last year.
