British fraud prosecutors are likely to file criminal charges against three former Icap brokers for their alleged roles in the manipulation of benchmark interest rates, according to people familiar with the case.

The expected criminal charges would be filed by the UK's Serious Fraud Office against Colin Goodman, Darrell Read and Daniel Wilkinson, these people say. The timing of the expected charges isn't clear. All three men were previously charged with fraud-related offenses by the US Justice Department last year.
