Adam Price has become the second Plaid Cymru Assembly Member to challenge Leanne Wood for leadership of the party.
The Carmarthen East and Dinefwr AM has confirmed that he will allow his name to go forward.
He joins Ynys Môn AM Rhun ap Iorwerth who confirmed his intention to stand earlier. You can read more details here.
Adam Price says he has been humbled by the encouragement and support:
The level of encouragement and support I received whilst not declaring any intention to stand has been truly humbling.
Earlier this week Adam Price said that Plaid has 'generally failed to consistently articulate a comprehensive and compelling vision of the future' and that to move forward it should have two leaders in future.
He'd also suggested that he wouldn't challenge if his proposal for Plaid to have two leaders were adopted.
Last night Leanne Wood issued this statement in response to his proposal:
I have always been in favour of collective leadership, of using all the talents at our disposal to get the best for Wales and its people. We have fantastic ability within our ranks - from our grassroots members, our town and community councillors, our county councillors and all the way up to our AMs and MPs.
The proposal was discussed by Plaid Cymru AMs in a group meeting yesterday but they decided it should be a matter for members of the wider party.
The Plaid Cymru Assembly Group has discussed the proposal for co-leadership put forward.
