AAP candidate MS Dhir has become Speaker of the Delhi Assembly with Congress issuing a whip to its MLAs to support his candidature.
37 MLAs support Dhir while 32 legislators back BJP candidate Jagdish Mukhi.
"We have issued a whip to our MLAs to support the AAP candidate," Delhi Congress President Arvinder Singh Lovely told PTI.
Opposition BJP fielded its candidate Jagdish Mukhi in the election scheduled later in the day.

AAP, which has 28 MLAs, needs the backing of eight Congress MLAs to secure the Speaker's post for itself. It can also count on the support of lone JD(U) MLA and an Independent who also backed the confidence motion.
