Liberal candidate Jordan Lane has been confirmed as the new MP for Ryde after a vote recount in the suburban Sydney seat.
The NSW election recount was ordered after weeks of counting left Mr Lane just 50 votes ahead of rival candidate Lyndal Howison, whose Labor party formally requested the new tally on Tuesday.
NSW Electoral Commissioner John Schmidt said on Thursday the call to recount was largely due to the very small amount of votes separating the two candidates, after preferences were distributed.
Other factors in the decision to hold a recount included the redrawing of the seat's electoral boundaries in 2021.
Labor holds 45 seats in the lower house and requires two crossbench MPs to pass legislation.
Mr Lane replaces outgoing Liberal minister Victor Dominello, who previously held Ryde by almost nine per cent.
