A group of Christians say Wales's national flag is "demonic" and should be changed.

The Welsh Christian Party claims the red dragon on the nation's standard is at odds with the country's position as a Christian nation. It wants the flag to be replaced with the black and gold cross of St David.

Party leader the Rev George Hargreaves said a symbol of the devil should not "reign over Wales for another moment". He said: "Wales is the only country in history to have a red dragon on its national flag.

"This is the very symbol of the devil described in the Book of Revelation 12:3. This is nothing less than the sign of Satan, the devil, Lucifer, that ancient serpent who deceived Adam and Eve in the Garden of Eden."

The party has launched an online petition calling for a referendum to allow the Welsh people to decide which flag they would prefer.

Historians and even fellow Christians said the symbol of the dragon had a "long tradition" in Wales and was a source of pride.
