 Significant criticism from unionist and Reform-aligned accounts over free childcare pledge backpedalling: "Plaid Cymru had FIVE 'main goals' in its manifesto — Rhun ap Iorwerth & his number 2 Sioned Williams have both BACKPEDDLED on TWO of those goals after less than 24 hours!" 
 "Sioned Williams couldn't say how it'll be funded, admitting 'we haven't started to plan out this work'. Plaid lied." 
 Some positive framing: "Plaid is putting poverty reduction and equality at the heart of government. Big promises. Big price tag. Big expectations." 
 Criticised as "open-border extremist" by unionist accounts
