An election in the US state of Kentucky has been decided by just one vote.

In a state-level race that was held during the US midterm elections, Democrat Jim Glenn beat Republican DJ Johnson 6,319 votes to 6,318.

According to the Associated Press, results from Mr Glenn's victory in Kentucky House District 13 were confirmed on Friday, after a review of the voting machine count.

The Kentucky State Board of Elections is due to certify the results next week.

"A win's a win - whether it's by one vote or 1,000," Mr Glenn told the Washington Post.

He said more than two dozen people had approached him since the news "and told me that they were the one vote that I won by".

But Mr Johnson told local outlet Tristate he is considering formally requesting a recount.

Social media in the US has lit up with news of the result.
