Former Test referee Wayne Barnes has expressed his support for changing the 'Dupont law' after a controversial weekend in the Six Nations. The law, named after Antoine Dupont, allows a player to be at least 10 metres from the receiver and stand still before being put onside. However, this can limit attacking opportunities and result in excessive kicking. Barnes, along with fellow ex-Test referee Nigel Owens, believes that the governing body should amend the law. Barnes also suggests that French assistant coach Jerome Garces may have played a significant role in the French squad's understanding of the laws.
