The countdown began on Monday to the UK general election due to be held on May 7.
The poll is being described as the most closely fought election in decades.
Parliament has been officially dissolved and Prime Minister David Cameron was driven to Buckingham Palace for a traditional audience with Queen Elizabeth.
Fierce battle for votes
Current polls suggest the ruling Conservatives and the main opposition Labour Party are neck and neck.
A latest Populus poll showed the number of seats each party is likely to win in the 650-member lower house of parliament.
The incumbent government is a coalition between the Conservatives and the Liberal Democrats.
At the last election, many people thought Labour and the Liberal Democrats were the natural parties to join together in coalition.
However, the Lib Dems, led by Nick Clegg, surprised even their own supporters when they decided to form a government with the Conservatives. Clegg became the Deputy Prime Minister.
The polling company ComRes had this recent opinion poll on the possible post-election scenarios:

Most polls give neither the Conservatives nor Labour enough votes to govern alone.
This means the winner will have to try to rule as a minority government, and rely on smaller parties for support on an issue-by-issue basis, or enter into a formal coalition deal.
David Cameron has said he wants another term in office to “finish the job” his coalition began in reforming the economy.

The government has imposed controversial tough austerity measures, arguing that the country has to learn to live within its means.
Parliament has been dissolved, but the incumbent government is still in charge until a new one is formed.
According to tradition and political conventions, no new policies can be announced by the incumbent government.
The main issues
Experts agree that these are the main issues at stake in this election: whether austerity is the best policy to tackle the budget deficit; the future of the National Health Service; immigration; and membership of the European Union.
But the two main parties, the Conservatives (Tories) and Labour, led by Ed Miliband, are focusing very much on economic stewardship.

The Tories claim they are the only ones competent enough to steer the country towards growth; Labour claims austerity has devastated many sectors of society and David Cameron’s stance on Europe is a danger.
The Prime Minister has promised to hold a referendum on European Union membership if he is reelected.
The future of Scotland is also an issue.
Nationalists in Scotland warn that if the UK pulls out of the EU, they would campaign for another independence referendum.
Those supporting independence for Scotland lost in a vote held last year.
Immigration is also high on the list of voter concerns.
The sensitive subject, along with debate about the EU, has been good for the UK Independence Party (UKIP).
The rise in the party’s support is seen as being thanks to its call for a sharp drop in immigration and a quick exit from the EU.
The issues will be battled out in a seven-way leaders’ debate on television on Thursday.
Other debates are also being held leading up to polling day.
