The Archbishop of York will be speaking at a special service ahead of the G8 summit in Enniskillen, Northern Ireland.
The service at St Macartin's Cathedral, Enniskillen, on Sunday has been organised by the Enough Food For Everyone IF campaign.
Dr John Sentamu will add his voice to thousands of campaigners asking G8 leaders to take action to end world hunger.
The IF campaign is pressing G8 leaders to take three steps:
- Clamp down on tax dodging and launch a convention on tax transparency to stop the flow of billions of pounds out of developing countries – money that could be used to end hunger.
- Help poor countries make sure that everyone, especially children, have enough nutritious food to eat and support poor families to grow their own food.
- Give people in developing countries more control over their land by protecting poor farmers from land grabs and using land to grow food not fuel.
Writing in The Telegraph recently, the Archbishop said the G8 summit was an opportunity to end global injustice and inequality.
He said: "We want an end to death from hunger and preventable disease. We want hunger and starvation to be eradicated. We want all to have access to basic medicines, treatment and clean water. We want a fairer tax system. We want everyone, regardless of where they live, to have the same life chances.
"That is why I and many others are supporting the Enough Food For Everyone IF campaign. Inside and outside the church we recognise that our country was built on the fundamentals of fairness, generosity, compassion and justice – and others should have the opportunity to do the same."
The service will be joined by singing group The Priests and local schoolchildren who will lead prayers on the themes of the IF campaign. Visitors from Africa and Asia will explain why political action is urgent.
A service in Westminster last week was attended by more than 3,500 people before taking part in an IF rally in Hyde Park joined by 45,000 people, including Bill Gates and Danny Boyle.
