Yes campaigners have claimed victory in the referendum on increasing the powers of the Welsh Assembly.
With one constituency still to declare, Say Yes For Wales campaign chairman Roger Lewis said he was delighted with the result.
He said: "It is clear, the people of Wales have spoken."
Vice chairman Lee Waters added that the group had won all of the constituencies bar one so far - Monmouthshire.
He said: "It is very clear that it is going to be a strong Yes vote for Wales.
"The No campaign made a lot of noise, got a lot of airtime but they did not win any votes."
First Minister Carwyn Jones also joined the celebrations in The Senedd. He said: "This has been a Yes vote across the whole of Wales."
Voters were asked whether they want the Assembly to have primary legislative powers in Wales.
Currently, the Welsh Assembly Government has to apply to Westminster for a Legislative Competence Order (LCO) in order for a law to come into effect.
