Kirsty and Sarah's favourite things are: Scotland, swimming, The World Development Movement (WDM), and providing entertainment for their nearest and dearest, at their own expense.

This year, we decided that it would be a really good idea to combine these things by swimming across a (really big) loch in Scotland. We thought this would be an opportunity to get fit.

Now, two weeks away, we've been to the lido three times (including both the time we forgot our costumes, and the time we spent so much time at the edge of the pool getting nervous and excited about our forthcoming adventure that we realised the pool had closed around us before we had swum more than three lengths).

So, to ensure we actually do it, and can provide the most top quality entertaining stories to you all, we though it both wise and worth for you to bribe us via WDM rather than paying into our whisky slush fund.

The World Development Movement (WDM) is a small UK-based anti-poverty campaigning organisation with a reputation for tackling hard-hitting, controversial issues in solidarity with campaign groups from across the world. In it's 40 year, WDM has had some amazing successes demonstrating that tackeling the structural causes of injustice is the best way to overcome poverty. WDM is currently campaigning to stop banks speculating on food and oil, which increases prices and causes hunger. It is also campaigning to tackle climate change justly, in a way that doesn’t simply reinforce existing global inequalities, and to get nationalised banks such as RBS to stop investing in projects which damage both the planet and human rights.
