Sunday trading: Welsh church concern over opening hours

A temporary extension to Sunday trading hours introduced during the Olympics comes to an end this weekend with some businesses calling for it to continue.
They say that in modern Britain, where shopping online is the norm, the law reducing trading hours is outdated.
However others argue that keeping the shops open longer is expensive, unnecessary and threatens to strain small firms.
Kayley Thomas chairs a debate between The Reverend Aled Edwards, chief executive of Cytun, Churches Together in Wales, and Mark Wallace, of the Institute of Directors, which represents business leaders.
