Safe standing football terraces rail-seat explained

In many European countries, football fans are allowed to stand at top-level games, something which is not allowed at premiership and championship matches in the UK.
All-seater stadiums were introduced in the UK following the Hillsborough disaster in 1989.
But campaigners say they have come up with a system which will make it safe for people to stand on the terraces.
Jon Darch, of the Safe Standing Campaign, demonstrates the "rail seat", which is due to be unveiled at Bristol City's ground on Wednesday.
