Plaid Cymru: Little faith in government to deliver alone
Regional development agencies, a national bank and more free childcare are among Plaid Cymru's demands as the party launched a "programme for opposition".
Leader Leanne Wood promised to deliver "the best deal for people in Wales", at a launch event in Treorchy.
Ms Wood pledged to hold the Welsh Labour government to account "with robust scrutiny".
She said there would be "great challenges" ahead in the wake of the vote for the UK to leave the European Union.
