Disabled wheelchair protest over welfare reform

Protesters in wheelchairs blocked a major street in London to protest government welfare reforms, which they claim push disabled people into poverty. The government argues the changes are necessary for financial reasons. Police negotiated with protesters to avoid heavy-handed tactics. The protest echoes past actions, such as those in 1997, where similar tactics led to policy changes. The government insists it is committed to supporting disabled people, but protesters vow to continue their fight.
