The Fleet News reporting team plus a panel of experts will be on hand to bring website visitors coverage of the Chancellor's announcements on key issues like BIK tax, fuel duty and tax on private fuel.
Fleet professionals will also be able to send any questions raised by the statement to the editorial team for immediate responses online.
Brown's statement is unlikely to contain any real surprises, although he has come under renewed pressure to soften the BIK tax blow by granting transitional tax breaks to high mileage drivers who will be hit hardest by next year's new company car tax regime.
The Chancellor will also confirm changes to the tax on free fuel for private mileage - making this former perk more expensive to drivers than paying for the fuel themselves.
Coverage starts at 3.30 p.m, with updates every 10 minutes.
