Politicians from all parties at Holyrood have backed a charity campaign to help some of the world’s poorest people.

The Scottish Catholic International Aid Fund’s (Sciaf) “Wee Box, Big Change” Lent appeal is to raise funds for its work providing emergency aid and practical support to people hit by hunger, poverty, war and disasters around the globe.

Deputy First Minister John Swinney, Conservative MSP Donald Cameron and Scottish Labour leader Richard Leonard all took part in a photocall outside the Scottish Parliament on Thursday to show their support for the latest campaign.

They were joined by Alison Johnston, co-leader of the Scottish Greens parliamentary group, and Scottish Liberal Democrat leader Willie Rennie.

This year’s campaign centres on Sciaf’s work to help vulnerable young people in Uganda affected by poverty, HIV and AIDS, and the legacy of war.

Last year, the charity helped more than 207,000 people in 27 countries in Africa, Asia, Latin America and the Middle East, with supporters in Scotland donating almost £1.7 million to the appeal.

Mr Swinney said: “The important work that Sciaf does through its appeals makes a huge difference to thousands of people struggling to survive.

“The generosity of people across Scotland is central to this and signals to our global neighbours that they can count on our continuing support in their time of need. I would encourage everyone to contribute to this appeal if they can.”

Mr Rennie said: “Donations will have a real impact on the projects in Uganda, and others around the world, supported by Sciaf and make a positive difference to each community.”
