Formula 1 boss Bernie Ecclestone should today hear whether he has won a multi-million pound High Court fight with a German media company.
A High Court judge is due to rule on the dispute between Mr Ecclestone, 83, and Constantin Medien at a hearing in London.
Mr Justice Newey had reserved judgment following a trial which ran from October to December.
During the trial, Mr Ecclestone was accused of entering into a ''corrupt agreement'' with a banker to facilitate the sale of the Formula 1 Group to a buyer chosen by him.
Constantin Medien says it lost out as a result of the deal and wants tens of millions of pounds in compensation.
Lawyers for Constantin Medien told the judge that payments totalling about £27 million had been made to Gerhard Gribkowsky - who had been a ''senior ranking official'' at a German bank - at the instigation of Mr Ecclestone.
And they said a ''corrupt arrangement'' was entered into between Mr Ecclestone and Dr Gribkowsky in 2005.
Mr Ecclestone, chief executive of the Formula 1 Group, said Constantin Medien's claim ''lacks any merit'' a nd he denied any conspiracy.
He told the judge that he had paid Dr Gribkowsky £10 million because the banker insinuated that he would create difficulties with tax authorities.
Mr Ecclestone is also facing a trial in Germany later this year after being accused of bribery. Those allegations also centre around claims relating to Dr Gribkowsky.
