A former Sunday Mirror investigations editor has pleaded guilty to illegally intercepting voicemail messages in 2001.
Graham Johnson, who worked at the Sunday Mirror between 1997 and 2005, is the first journalist from the Mirror Group of newspapers to admit phone-hacking.
Johnson voluntarily contacted police in 2013 and admitted his role in hacking the voicemail messages of prominent personalities.
The former reporter will be sentenced on 27 November.
Trinity Mirror, which owns the Sunday Mirror and Daily Mirror as well as a number of other newspaper and magazine titles, admitted that its journalists were involved in phone-hacking in September.
