The Guardian newspaper has lost its head of legal Nuala Cosgrove to media regulator Ofcom.
Cosgrove, who was director of editorial legal services at Guardian News & Media (GNM), will join Ofcom in the new year. She will report to general counsel Polly Weitzman and work on Government policy issues.
GNM, which publishes The Guardian and The Observer, is still in the process of finding a replacement for Cosgrove.
During her six years on The Guardian’s legal team, Cosgrove worked on a number of cases that kept contentious stories on the paper’s front page.
Last year she secured the publication of a cash-for-honours story that the BBC was barred from revealing.
The Guardian revealed that detectives were investigating whether Lord Levy, the Labour Party’s chief fundraiser, had urged one of Tony Blair’s senior aides to shape their evidence to Scotland Yard.
Cosgrove was also called in to advise on The Guardian’s exposé of BAE Systems’ alleged bribery of Saudi Arabian officials to secure defence contracts.
Cosgrove began her legal career in 1994, spending five years at Stephens Innocent – now Finers Stephens Innocent – before moving to fashion house Burberry, where she worked as in-house legal counsel for two years.
After a year at Davenport Lyons, Cosgrove joined The Guardian’s in-house team in 2002, becoming head of legal last year.
Cosgrove declined to comment, but did confirm the move.
