Sexist stereotypes, humiliating photographs of women and male bylines dominate the front pages of British newspapers, according to research carried out by the industry body Women in Journalism.

Male journalists wrote 78% of all front-page articles and men accounted for 84% of those mentioned or quoted in lead pieces, according to analysis of nine national newspapers, Monday to Saturday, over the course of four weeks.

The only women to be regularly photographed in the period were the Duchess of Cambridge, her sister, Pippa Middleton, and the crime victim Madeleine McCann. The three men most likely to be photographed were Simon Cowell, whose biography was published that month, Nicolas Sarkozy, who was fighting an election, and Prince William.
