Graham Norton earned more than £4.5m last year after profits from the production company he founded boosted his BBC salary.
The presenter who has a £2m-a-year pay deal with the BBC, took home an additional £2.5m from So Television, which makes programmes including his BBC1 series The Graham Norton Show.
Norton earned £2.15m in "production fees and royalties" from So Television in the 12 months to 31 July 2011, according to accounts filed at Companies House. The payout was a 40 per cent increase on the £1.54m he received for those services in the previous year.
Norton, who co-founded So with producer Graham Stuart in 2000, was also paid a £400,000 dividend by the company, taking his total payment to £2.55m, a 28 per cent increase on the previous year.
So Television, which employs 23 staff, reported a revenue increase of 37 per cent from £8.7m to £11.9m. Its success last year came from expansion in production and distribution of programmes, including Pixelface, a children's sitcom made for CBBC.
Norton's chat show has turned down a request by Sacha Baron Cohen to appear because he refused to be interviewed as himself, rather than in the character of his latest comic film, fictional dictator Admiral General Aladeen.Reuse content
