Models, muses and a rich cat: new film spotlights unusual life of Karl Lagerfeld

A BBC Two documentary looks at the late designer's life and finances through the eyes of his friends

The legal fallout from the death of Karl Lagerfeld four years ago is still heavily draped in secrecy. But, ahead of a major exhibition of the great German clothes designer's work in New York, a new BBC documentary is about to offer a glimpse of his unusual private life and shed light on his enormous financial legacy.

While Lagerfeld's vast Parisian apartment remains sealed and his 150m estate is tied up in protracted negotiations between lawyers in Monaco and Paris, it has emerged that the leading beneficiary of his will is set to be the 33-year-old French model Baptiste Giabiconi.
