Leanne Wood was elected leader of
Plaid Cymru in
March 2012 with 57% of the vote, defeating
Elin Jones and
Dafydd Elis-Thomas. Under Plaid Cymru's constitution, the leader is subject to re-election every two years, but this is usually uncontested. The window for any leadership challenge closed on 4 July 2018, when Wood was challenged by two of her Assembly colleagues. Wood submitted her nomination papers in June 2018. Wood admitted that she was preparing to resign following Plaid's results in the
2017 general election until the result in
Ceredigion came through showing a Plaid Cymru gain. During the summer of 2017,
Rhun ap Iorwerth publicly announced that it would be 'very probable' that he would stand when a vacancy arose. On 13 June 2018 Wood stated that she would resign as leader in 2021 if she failed to become First Minister. She had previously stated that she would welcome any challenge to her leadership. The
Carmarthenshire Plaid council group wrote to encourage
Adam Price to stand against Wood. On 26 June former MP
Elfyn Llwyd said in a
BBC Radio Cymru podcast that "[Plaid Cymru has] been standing still for five to seven years now and perhaps that suggests that it's time to change the team." On 1 July 2018, fifty-three (out of about 200) of Plaid Cymru's principal Councillors wrote to pledge their allegiance to Leanne Wood ahead of any potential leadership challenge. ==Campaign==
