About Plaid Cymru
Plaid Cymru (the Party of Wales) is a centre-left Welsh nationalist party that campaigns for Welsh independence, the Welsh language, and social justice. Founded in 1925, the party holds seats in both Westminster and the Senedd (Welsh Parliament). Plaid's support is concentrated in Welsh-speaking areas of north and west Wales, though it has made efforts to broaden its appeal in south Wales valleys and urban areas.
