A BNP candidate for the Welsh assembly is due in court on Monday after police were passed a video appearing to show him burning a copy of the Koran.
Sion Owens, aged 41, has been charged with a public order offence.
Joanne Shannon, another BNP candidate also arrested in connection with the incident, has now been released on police bail.
Mr Owens, a BNP candidate for the South Wales West regional list, is due before magistrates in Swansea.
A BNP spokesperson said both would still be candidates in the assembly election on 5 May.
South Wales Police said Mr Owens was arrested on Friday when the force was passed a video recording showing a man, who appeared to be Mr Owens, burning the Koran.
He was taken into custody at 20.45 BST and charged on Saturday evening under the Public Order Act.
Joanne Shannon, a BNP candidate in in Swansea East, was arrested at the same time.
She has been released on police bail, pending further inquiries.
Last week in Afghanistan seven United Nations workers were killed in the city of Mazar-i-Sharif.
It was reported that it happened partly in relation to the burning of a copy of the Koran in America.
That happened in a small church in Florida after controversial pastor Terry Jones judged the holy book to be "guilty" of crimes.
But Terry Jones denied it led to events in Afghanistan.
