The idea of a single, flat-rate pension was first floated by the Work and Pensions Secretary Iain Duncan-Smith earlier this year. Then the chancellor, George Osborne, confirmed plans to simplify the state pension in this year's Budget.

The government has now put forward proposals in a Green Paper for a single-tier, flat-rate pension of around £140 per week. Experts believe the changes would benefit seven million pensioners while another five million would lose out. Find out who the winners and losers are.
