Turnout and LAB majority
Experts say young voters were key to Labour's success in Wales.
Albert Owen, who retained the marginal Ynys Mon seat for Labour, attributed his victory to a young vote.
And Ben Lake, the country's youngest MP at 24, who took Ceredigion for Plaid Cymru, said young people "created excitement" in his local campaign.
Ynys Mon AM Rhun ap Iorwerth said Plaid Cymru is disappointed at not winning the parliamentary seat at the general election.
The party's former leader Ieuan Wyn Jones failed to return to Westminster as the party slipped to third in the constituency.
Albert Owen is re-elected in Ynys Mon.

Plaid Cymru had targeted Ynys Mon to try and take the seat from Labour, who have a narrow majority of 0.66% there.
But a party source has told our reporter Mark Hutchings that it "currently looks unlikely" they will win it.
The source claimed Plaid had been squeezed by the "polarised" Conservative/Labour narrative.
A senior Labour source in north Wales says despite the gloomy exit polls for the party in the Wrexham and Clwyd South constituencies, the party remains confident of holding both seats thanks to a strong youth vote.
Meanwhile in Ynys Mon, Plaid Cymru sources say the campaign has been a "struggle", while the Conservatives say they've been "greeted positively" on the doorstep. But both concede the Labour vote there seems to be holding up well.
The seat held by First Minister Carwyn Jones in the assembly is deemed "too close to call" in our general election forecast.
Following analysis of the exit poll, it's suggested that the Conservatives have a 23% chance of winning Bridgend. The seat has been targeted by the Tories, and Theresa May made a campaign visit here early in the campaign.
Newport East and West and Ynys Mon are also in the "too close to call" category".
In Ynys Mon, it's suggested that Plaid Cymru has a 32% chance of victory over Labour.
