The former leader of Plaid Cymru Ieuan Wyn Jones has said that the party needs to develop a stronger national strategy and electoral machine outside of its traditional strongholds.
Speaking to S4C's Newyddion, the former Deputy First Minister said that while the party's organisation was particularly good in constituencies such as Ynys Môn, Arfon, Ceredigion, Dwyrain Caerfyrddin a Dinefwr, and Dwyfor Meirionnydd the same could not be said for areas outside of these strongholds.
Jones said that this was a "shortcoming" that the party needed to "look at seriously", adding that "it's not just about money, it's about getting people to work locally."
Jones said that the party needed to do more to appeal to voters in other parts of the country: "If you are going to succeed in forming a government you have to appeal beyond your core supporters."
Despite gaining an extra regional seat, Plaid fell behind the Conservatives to finish third in the election.
