Just a Drop appoints Pointless star

International water aid charity Just a Drop has appointed Alexander Armstrong as a patron.

The BAFTA winning comedian, actor, TV presenter and host of TV quiz Pointless, joins the charity that was set up in 1998.

Armstrong described the charity, set up by Fiona Jeffery OBE, as "a small organisation that achieves a colossal amount all over the world".

Over one million people have benefited from clean water projects since Just a Drop was formed.
