"Due to cost overruns the UK's funding agency for particle physics and astronomy, STFC, is recouping £80M with deep cuts to UK physics operations in these areas. These include ending the UK's involvement in the International Linear Collider - the next generation of particle physics experiment. This risks relegating the UK to second tier involvement in future research and critically damaging the country's standing within the community. Furthermore UK Astronomy will be seriously hit with up to a 25% cut in grants. This is incompatible with the government's stated aim of making Britain a world leader in science. A review of this decision has recently been announced and we urge the Prime Minister to press for another solution to this problem before UK physics is set back by decades."
