The trade union Unite has organised a protest in Knightsbridge to coincide with the first anniversary of the introduction of the "bedroom tax". Unite wants a vote to end the policy, which was meant to encourage council tenants to move into smaller properties if they were in houses with a spare room.
Opponents say it has left many tenants forced in to paying more for their current houses as there aren't enough smaller properties available for them to move into. The government has said the scheme is not a tax and instead refers to it as "the spare room subsidy".
