At the end of the debate, pro-tem Speaker Matin Ahmad asked those in favour to stand up followed by those against.
Later, he declared the motion as passed and congratulated the Chief Minister before adjourning the house.
28 AAP members along with seven of Congress, a lone JD(U) member and an independent stood in support while 31 members of BJP and one member of its ally Akali Dal stood against it.
The fate of the motion was a foregone conclusion after Congress leader Arvinder Lovely declared that his party's seven members would support the government and said the backing would continue as long as the regime works in the interest of the people, even for five years.
However, the BJP opposed the confidence motion and accused Kejriwal of compromising with the "corrupt" Congress for power and becoming silent on the corruption of the previous Congress government.
