An animal welfare charity said all halal meat produced in the UK should undergo pre-slaughter stunning to prevent animals suffering distress.
Amid a furore over high street restaurant chains serving halal meat, Philip Lymbery from Compassion in World Farming told ITV's Good Morning Britain: "The real issue is whether the animals were slaughtered without pre-slaughter stunning."
He said that currently around 90 percent of animals used for halal meat in the UK are stunned before being killed - a process that desensitises them to pain and distress.
