So, ahead of the outcome’s announcement, has President Narendra Modi reacted to the polling trends?
It is the diplomatic custom for foreign leaders to wait for the full election result to be announced, unless one side concedes, before commenting.
Mr Modi has yet to formally react to the results and is likely awaiting official confirmation of the outcome before commenting.
The Indian Foreign Ministry is also yet to issue any statement.
The election frontrunner, former cricket superstar Imran Khan, has had a contentious relationship with Mr Modi.
In 2014 he described him as a “faithful man” and praised his efforts to combat corruption.
The two men met one year later after which Mr Khan claimed he’d raised the “plight of minorities in India”.
However during the election campaign Mr Khan adopted a provocatively anti-Modi position.
He accused Mr Modi of having an “aggressive anti-Pakistan posture” which he blamed for the poor relations between the two countries.
Mr Khan also attacked his electoral opponents over their supposed friendliness towards Mr Modi and India.
He accused his main rival, Shehbaz Sharif, of “speaking Modi’s language” and “protecting India’s interest” after he admitted Pakistani groups were involved in the brutal 2008 Mumbai terror attack.
Supporters of Mr Khan adopted the provocative chant: “A friend of Modi is a traitor”.
Mr Khan also attacked another rival, former prime minister Nawaz Sharif, over his relationship with Mr Modi.
He claimed: “India loves Nawaz. Modi loves Nawaz. But they hate our Pakistani forces.”
He went on to accuse Mr Sharif of “protecting India’s interests”.
