LONDON : Former Murdoch executive Rebekah Brooks on Thursday denied knowing anything about phone hacking while she was editor of Britain’s News of the World tabloid, as she took the stand for the first time in her trial.

Brooks is charged with hacking, bribing public officials and two counts of trying to cover up her alleged crimes, although she was cleared of a fifth charge of approving a payment for a photo of Prince William in a bikini. Almost three years after she was first arrested in July 2011 and three and a half months into the trial, the former chief executive of Rupert Murdoch’s News International newspapers finally had a chance to put her side of the story.

Brooks was asked by her lawyer if she had ever heard mentioned the name of Glenn Mulcaire, a private detective who worked for the tabloid while she was editor and was jailed in 2007 for phone hacking.

Seated in the witness box at London’s Old Bailey court in a blue dress and white cardigan, her red curly hair pinned back, she replied: “No”.

When asked if hacking had ever been brought to her attention, Brooks replied: “No, not at all.”

The 45-year-old acknowledged that private detectives were used at the News of the World but added: “It is common practice in Fleet Street.”

Brooks edited the Murdoch tabloid from 2000 to 2003 before becoming editor of its sister paper, The Sun. In 2009 she was promoted to chief executive of all Murdoch’s British newspapers in the News International group.

She resigned in July 2011, a few days after Murdoch shut down the News of the World over the hacking scandal and a few days before she was arrested.

Before Brooks began giving evidence, the judge ordered the jury to find her not guilty on one of the five charges against her, that of conspiring to commit misconduct in public office.

Brooks was accused of sanctioning a payment of £4,000 ($6,700, 4,900 euros) to a public official for a picture of Prince William dressed as a bikini-clad Bond girl at a party at Sandhurst, the British army’s officer training school.

The image was never published but led to a story in The Sun in September 2006 with the headline “Willy in a Bikini” together with a mocked-up picture of the second-in-line to the throne in a green swimsuit.

In her testimony, Brooks described how she began her career as an inexperienced young journalist, and lifted the lid on the highly competitive male-dominated world of tabloid newspapers.

Recalling an incident where her phone wires were cut by colleagues in a prank, she said: “There was probably a bit of old-school misogyny.”

She talked about some of her greatest scoops, including an interview with Divine Brown, the Hollywood prostitute caught having sex with actor Hugh Grant in 1995.

The story cost the News of the World £250,000, she said, adding: “It was probably one of the biggest expenses that I had ever dealt with.”

In his opening statement, Brooks’ defence lawyer Jonathan Laidlaw urged the jury to focus on the charges.

He said she was not on trial for being the editor of a tabloid newspaper, for working for Murdoch or for the policies and corporate views of his company.

“There are agendas as you can all see, being pursued elsewhere, so please just be careful and keep an open mind and stay focused upon what matters,” Laidlaw said.

On the hacking charge, the key question was whether Brooks knew about and endorsed the practice while she edited the News of the World.

On the charge of conspiring to pay a public official for a story while she edited The Sun, her lawyer said the issue was whether she knew the official was the source.

The third question was whether as alleged, Brooks instructed her husband Charlie and her personal assistant Cheryl Carter to cover up her alleged crimes.

Brooks, her husband and Carter are among seven defendants in the trial, including Andy Coulson, her successor as editor of the News of the World and one-time lover.
