New Downing Street site is trendy, but is it accessible?

The new Downing Street site has all the trendy social media clichés covered. You can watch their videos on YouTube, even follow the PM's Twitter feed and like all good 'web 2.0' sites it's in BETA!
However, they've been so busy getting 'down with the kids' they seem have forgotten about making the site accessible to disabled users.
Research by AbilityNet has found a whole gammut of failings that make the new site difficult or impossible for people with some impairments to use. It's the sort of thing you might expect from some small startup but not from the Prime Minister's office and the disabilisphere is already kicking up a storm, let's make sure they consider access first before image in future!
