Image source, PA MediaSir Keir Starmer says he has spoken to Eluned Morgan after her historic election which has seen the Welsh Labour leader lose her seat in Ceredigion Penfro.
In a statement the prime minister says: "Eluned Morgan has been a formidable first minister and tireless champion for Wales.
"She broke barriers and has never stopped fighting for families in the communities she loves.
"Together, we have worked to lift children out of poverty, cut hospital waiting lists, and create thousands of new jobs."
He thanks Morgan for her "over 30 years of service" to the country and to Labour, and adds: "I have no doubt her contribution to Wales will endure."
More from Eluned Morgan's speech after her defeat, as she argues Labour needs to go back to being the "party of the working class".
"It is clear that results across the whole of the United Kingdom have demonstrated deep frustration with the Labour Party," she says.
"We need the Labour government nationally to change course. We need the wealth of this nation to be more equally distributed away from the south east.
"But I was always clear that this election was about Wales and Keir Starmer was not on the ballot."

Eluned Morgan says she is "stepping down as leader of Welsh Labour" in a speech after losing her seat.
Morgan says she takes responsibility for the Labour result in Wales, and that the people of Wales "rejected Welsh Labour".
She says that being first minister has been the "privilege of my life" and as the first woman to lead the nation.
Eluned Morgan becomes the first leader of a government in the UK to lose their seat while in office.
This election was historic enough without the defeat of the Welsh first minister in Ceredigion Penfro.
The Senedd vote also ends a century-long run of Labour election successes in Wales.
