The left-wing Socialist Alliance is to launch its manifesto today with policy proposals including a minimum wage of £7.40 an hour, a state pension of £150 per week, higher income tax and the abolition of the monarchy.

Many of the SA's members are defectors from the Labour Party who believe that Tony Blair is too right wing. Prominent leaders include MSP Tommy Sheridan, councillor Dave Nellist, former Labour MP and former Labour executive committee member Liz Davies.
