Kate Middleton's name was on a list of potential phone hacking targets found at the home of a private investigator hired by the News of the World, a court has heard.
The jury at the Old Bailey was shown a handwritten note in 2006 by Glenn Mulcaire entitled "Target Evaluation", featuring a list of 18 names. At the time, Middleton was dating Prince William.
As well as the name of the current Duchess of Cambridge, PR guru Max Clifford, Mayor of London Boris Johnson and former England football manager Sven Goran Erikson also featured on the list.
However, while prosecutor Andrew Edis QC said Middleton's name would feature "in a passage of the evidence" in the phone hacking trial, Johnson was not involved in the case.
Other names of Mulcaire's list included Wales manager Chris Coleman, footballer David James, Kerry Katona, Tom Parker Bowles, Matthew Doyle, an aide to former Prime Minister Tony Blair and Jamie Lowther Pinkerton, former private secretary to Prince William.
Mulcaire has already pleaded guilty to to three counts of conspiracy to hack phones. He was jailed in 2007 for hacking the phones of royal aides on behalf of the now defunct NotW.
The list of potential targets from Mulcaire was discussed in court in relation to the alleged phone hacking of Eunice Huthart, a former double for Angelina Jolie. The court heard how Huthart was targeted by the newspaper between 2005 and 2006 while there was huge media attention between the relationship Jolie and Brad Pitt.
Huthart said she had complained to Vodafone because her voicemail PIN number was not working in Los Angeles, where she stayed while working with Jolie on the film Mrs And Mrs Smith, alongside Pitt.
The court heard how her details were also found in Mulcaire's notebooks. Phone records revealed he accessed her unique voicemail number on four occasions.
A statement from Huthart read out in court said: "I would have my phone off and only turn it on to pick up my messages to avoid excessive roaming charges.
"Every time I went into my messages, the PIN code didn't work."
Former NotW Rebekah Brooks and ex-Tory spin doctor Coulson, along with six others, are accused of conspiring to hack phones and corrupt payments to officials. Brooks also faces two counts of conspiracy to pervert the course of justice destroying notes and computers which could have been used as evidence against her.
The trial continues.
