Birmingham council—the largest in England—voted to call for the bedroom tax to be scrapped last week, while anti-bedroom tax campaigners lobbied outside.
Councillors were under pressure after cancer patient Veronica Kenning denounced the bedroom tax.
She has been threatened with eviction and called the Labour council’s suggestion she apply for Discretionary Housing Payment “an insult”.
The council has released figures revealing it has just 75 one-bedroom council flats with more than 11,000 people chasing them.
The figures forced Tory bedroom tax minister Lord Freud to admit that there are “virtually no single bedrooms” in council and social housing.
Other campaigns are preparing lobbies of other councils. There will also be a national day of action on Saturday 26 October.
And campaigners in Scotland were set to demonstrate at the Scottish National Party (SNP) conference on Saturday.
SNP leader Alex Salmond demands the bedroom tax is scrapped.
But he is under pressure from campaigners and Scottish Labour to amend Scottish law and rule out evictions from any landlords.
