The budget for the 2014 Commonwealth Games in Glasgow is to be increased by £80m, BBC Scotland understands.
The bulk of the money will come from the Scottish government and Glasgow City Council.
It is thought some of the extra cash will be used to enable the games to be broadcast on high definition TV.
The original budget for the games was set at £373m but more funds are said to be required as a result of the global economic recession.
It is understood global economic circumstances have changed the figures originally outlined to cover the cost of staging the games.
An announcement on the additional funding is expected to be made early next week.
