In a statement released, Sullivan rejected the allegations and criticised the reporting surrounding them.
He said: "I have recently become aware that factually incorrect and entirely false, decades-old allegations concerning my personal life are due to be broadcast and published.
The false allegations levelled against me have been sensationalised by the media.
I am a private man, and those who personally and professionally know the real David Sullivan, not the caricature invented by the tabloids, know exactly who I am and what I stand for.
The billionaire also vowed to pursue legal action, stating: "I will be suing the BBC for libel, along with any other media outlet that repeats any libelous allegations."
