In the heart of the city, in the middle of these office blocks, hundreds have gathered to protest.
This is the building where protesters want to disrupt; the non-descript head quarters of ATOS. Paralympics sponsor, but also the company contracted by the government to review - and in some cases cut - the help disabled people in Britain get.
The government has asked ATOS to reassess all 2.6 million people on disability benefit by 2014, in an effort to cut the welfare bill.
