5.In April 2011, the Government published a Green Paper, A state pension for the 21st century (Cm 8053), which consulted on two broad options for reforming the state pension system for future pensioners. The White Paper which followed in January 2013, The single-tier pension: a simple foundation for saving (Cm 8528), outlined the Government intentions for reforming the state pension. Those proposals form the basis for the measures in Part 1 of the Act.
