SO VALUABLE is the power of Instagram that model agents negotiate specific clauses in their clients’ contracts, with a fee for an Instagram post of the campaign pictures in which the model stars.

Cara Delevingne is the UK’s highest-paid model and her posts include several marked as a paid partnership with sports brand Puma, for whom she endorses her own range. Marketing experts say she is thought to be paid more than £2 million a year.

The 28-year-old also has a contract thought to be worth £1 million with Dior, name-checking the brand several times, along with two paid-for posts for watch brand TAG Heuer.
