On Tuesday 17 December the government published its Green Paper on pensions.

The Green Paper set out how the government plans to tackle the UK pensions crisis.

A spate of issues, ranging from closures of work pensions to the state of the stock market, have once again pushed the issue of pensions into the national spotlight.

As part of BBC News Online's special coverage of the UK's pensions crisis, Malcolm McLean, chief executive of the Pensions Advisory Service (Opas) has agreed to answer some of your questions about pensions and pensions reform.

Opas is a non-profit organisation which helps members of the public to resolve pension problems.

Malcolm's responses will appear shortly.

The opinions expressed will be Malcolm's, not the BBC's. The answers are not intended to be definitive and should be used for guidance only. Always seek professional advice for your own particular situation.
