Head of London's police force Cressida Dick resigns after string of scandals

The head of London's Metropolitan Police, Cressida Dick, said Thursday she is resigning after a string of controversies that undermined public confidence in the force and prompted a falling out between her and the capital's mayor. Mayor Sadiq Khan had recently threatened to oust Dick from her role, saying she wasn't doing enough to reform the Metropolitan Police, Britain's largest police force, and tackle growing accusations of misogyny and racism.

Khan said late Thursday it was clear the only way to overhaul the force was to have "new leadership right at the top of the Metropolitan Police."

In a statement, Dick, who has headed the force for four years and is the first woman to lead Scotland Yard, said it was with "huge sadness" that it has become clear that Khan "no longer has sufficient confidence in my leadership to continue."
