The prime minister Gordon Brown will tomorrow announce that the general election will take place, as expected, on May 6.
The Labour leader will go to Buckingham Palace in the morning to ask the Queen to dissolve parliament.
Political analysts have predicted the election will be the closest in years.
A poll commissioned by the Guardian newspaper puts the Conservatives only four points ahead of Labour.
The election campaigns are likely to be fought on the economy, taxation and potential cuts to public services.
General elections are traditionally periods of uncertainty for the corporate travel sector, and travel volumes are predicted to slow slightly at the start of May.
In terms of policies, business travel industry leaders will be hoping for focus on three key areas: tax, high-speed rail and airport expansion.
The Chancellor's failure to address air passenger duty in the recent budget left many in the industry angry.
A majority consider APD to be a stealth tax which was brought in to exploit the travel and aviation sectors when climate change prevention started to command political currency.
No political party has given any indication that APD will be scrapped or modified if they take power.
The Guild of Travel Management Companies (GTMC) launched its first business travel manifesto earlier this year, the organisation's first ever move into the political arena.
The manifesto claimed that business travellers had high-speed rail highest on their list of concerns, an issue being approached by each of the political parties. All appear to be committed to investment in this area.
Perhaps the most pertinent issue facing the business travel sector is that of airport expansion.
The Labour party has already committed to building third runway at Heathrow. The Tories, however, have pledged to scrap the project should they win power.
