The Parliamentary Office for Science and Technology (POST) offer an internship scheme for EPSRC PhD students. I had a go at applying, but didn’t get the place (a pity really).
Anyway, the task set to rank applicants was to write a two-sided brief on volcanic ash that would be understandable and accessible to a politician. Just in case it might be useful to anyone, I’ve put it up on here.
You can read the all the back-catalogue of POST briefs on key tech areas online here. Some are really interesting and I encourage you to check them out!
