Johnny Depp to testify at defamation trial

Actor Johnny Depp is expected to take the stand on Tuesday in his $50m (£38m) defamation trial against ex-wife Amber Heard, who he accuses of sullying his reputation.

The lawsuit is over an opinion piece Ms Heard wrote for the Washington Post in which she calls herself a victim of domestic violence. He denies any abuse.

Ms Heard has filed a counterclaim.

The closely-watched civil trial, which is taking place in Virginia, is now in its second week.

The jury has heard evidence presented by the celebrity ex-couple's former therapist, who described how Mr Depp and Ms Heard engaged in "mutual abuse", as well as from medical workers who treated Mr Depp as he was detoxing himself from opiates.

The trial has focused so far on Mr Depp's demeanour and whether he was ever verbally or physically abusive towards Ms Heard. Lawyers for Mr Depp have accused his ex-wife, who is also an actor, of giving the "performance of her life" in her descriptions of alleged abuse.

On Monday, a nurse who was hired to treat Mr Depp's drug addiction and attended the couple's wedding testified that she witnessed Ms Heard "try to instigate" conflict with her former husband on several occasions.

She would sometimes pick fights with him while he was receiving medical treatment, said nurse Debbie Lloyd, who frequently travelled with Mr Depp.

On Tuesday, a sound engineer who has worked with Mr Depp on nearly all of his movies since the 1990s testified to having never witnessed the actor verbally or physically abuse his two children or their mother.

Keenan Wyatt, who is also a friend of Mr Depp's, described how the actor wears an ear piece during filming to listen to music and occasionally have lines fed to him.

The trial is expected to last at least six weeks, and jurors have so far been presented with duelling accounts of Mr Depp and Ms Heard's relationship.

Ms Heard's team has portrayed Mr Depp as an abusive partner prone to drug and alcohol binges.

Mr Depp's team has presented Ms Heard's claims of domestic violence as a "hoax" and a calculated strategy to ruin his reputation.

Ahead of the trial, Ms Heard wrote on social media that she never identified Mr Depp by name in her 2018 op-ed.

"Rather, I wrote about the price women pay for speaking against men in power," she said.

"I continue to pay that price, but hopefully when this case concludes, I can move on and so can Johnny".
