They are a major political party in Wales, and, AFAIK, they’re committed to greater devolution rather than independence for which there’s far less public support than in the other devolved nations (6% in the last poll I saw versus 45% for in the Scottish referendum).
I’m not Welsh but I think it’s a pity we don’t have more politicians with Wood’s instinct and acumen in the rest of the UK. This is just another instance of a politician getting it spot on about Morrissey. The last time that happened was when David Cameron came out as a Smiths fan; finding myself in accord with Leanne Wood leaves me feeling less icky.
(I have three in the troll vote sweepstake, by the way)
