Plaid's green call as conference ends
The Plaid Cymru leader Leanne Wood has been promoting the benefits of small green energy projects, during a trip away from her party's conference in Brecon.
It came as delegates backed a call for police officers to be brought to justice, who covered up the truth behind the Hillsborough disaster.
Plaid's Westminster leader Elfyn Llwyd said the affair calls into question the moral authority of the state.
