Question: what flag is green and white with a red dragon?
Answer: Graham Bartram, of the Flag Institute, said: "The Welsh flag we know today - a large red dragon on a white and green background - only came into being in 1959. "But, in fact, the red dragon as an emblem has been used in Wales since the reign of Cadwaladr (Cadwallader), King of Gwynedd from around 655AD."
