Prince Charles 'tried to influence NHS policy' in Wales
Former cabinet minister Peter Hain says Prince Charles encouraged him to press the Welsh government to introduce complementary medicine on the NHS.
Mr Hain said they had discussed it when he first became Welsh Secretary.
The Labour MP for Neath added such conversations between the Prince and Welsh secretaries took place regularly.
Mr Hain's comments are on a BBC Radio 4 documentary about the future monarch's conversations with politicians.
A spokeswoman for the prince would not comment on private conversations.
