"One of the most fascinating things about the government's wobble on welfare this week has been the critical role of a new breed of disability campaigner in successfully marshalling public and political opposition to the reforms." writes Patrick Butler, Head of Society, Health and Education at the Guardian, today.

The extraordinary triple victory on specific benefit issues in the House of Lords on 11 January 2012 has raised questions for a number of people about the larger situation regarding the Welfare Reform Bill. Some of the bill might be helpful, but I want to be very clear today about which parts sick and disabled campaigners know to be unacceptable - and why.

The campaign to challenge the government's welfare reforms (which as well as introducing necessary simplifications are also about making £18 billion worth of cuts and targetting the most sick and vulnerable in society) has made extraordinary use of social media in the past few days.
