Here is the full text of Gordon Brown's letter to Labour members on the party website:
Last week we came together as a party to debate the choice for Britain.
In the next few months I will tour the country, meeting the people of Britain to explain our policies, not just on economic recovery and Afghanistan, but from Sure Start and school standards to social care, the NHS, and action on anti-social behaviour.
I will visit every region and every city to speak to people and discuss with the people of the country the choices we face.
I have already said that we are facing the first General Election of the global age. In it the choices are great: between different directions for our country, different choices about economic progress, different philosophies about the future of our public services, different pathways in our relationship with Europe and the rest of the world.
It is right that the parties debate the issues not just in Parliament but in every arena where the public will join in
In momentous times like these, the choices cannot be small choices with small consequences: they are big choices with big consequences.
The choices we make in the next year will define the future of our country, not just for five years, but for a generation to come.
So I believe it is also right that the parties debate the issues not just in Parliament but in every arena where the public will join in the discussion.
It is right that we set the issues before the British people. Others can work out the details but what's important for the country is that there is a wide ranging series of television and radio debates with party leaders that are also able to devote attention to the central issues that matter to families: the economy, public services, how we strengthen our communities, and how we work with the rest of the world.
It is right that there will be a strong focus on the leaders' debates and it is right that in a Cabinet system of government that ministers and opposition ministers also debate the issues in a series of debates on television and radio too.
I relish the opportunity of making our case directly to the people of this country.
