CNN awarded Hillary Clinton an overwhelming victory in the first presidential debate - but most snap polls show Trump emerged victorious. 

Trump and Clinton tangled over the economy, her use of a private mail server and his unwillingness to release his income tax returns on Monday night. 

They engaged in a vigorous back-and-forth on the debate stage at Hofstra University in Hempstead, New York, as polls showed them locked in a tight race. 

However, after the debate's end, polls conducted by a number of media websites showed their readers felt the real estate mogul came out on top.

Trump acknowledged the result, tweeting: 'Wow, did great in the debate polls (except for @CNN - which I don't watch). Thank you!'

CNN/ORC's snap poll, gave Clinton the win with 62 per cent to Trump's 27. 

It was the biggest, and fastest, exercise conducted by an opinion polling firm. 

The poll of 521 registered voters who watched the debate was a sample which the network warned leaned more Democratic than the average - starting the night with Clinton ahead 26 per cent among the sample.
