Richard Wallace has been named the new editor of the Daily Mirror, following the recent departure of Piers Morgan.
The Daily Mirror apologised after publishing the fake photographs
Wallace, 43, currently deputy editor of the Sunday Mirror, will take up his new position with immediate effect.
Morgan was sacked after publishing photographs - later shown to be fakes - that purported to show British soldiers abusing Iraqi prisoners.
Des Kelly, acting editor of the Daily Mirror for the past five weeks, is leaving the company.
Wallace is a former showbusiness editor, US editor and head of news at the Daily Mirror, and has also held reporting roles on the Daily Mail and the Sun.
He has been acting Sunday editor for the past four months while editor Tina Weaver is on maternity leave.
He said: "I'm absolutely delighted to be given the opportunity to lead this great newspaper, especially as I'm going to be working with the most talented team in Fleet Street.
"The greatest challenge for national newspapers is circulation. I'm confident that we have the team, the talent and the will to tackle this challenge and I look forward to even greater success for the Daily Mirror."
Ellis Watson, the new managing director of Trinity Mirror - the paper's owner, said: "Richard has bags of ability and huge experience in tabloid newspapers.
"The Daily Mirror has a fabulous heritage and Richard's job will be to build on that as we go forward.
"With his talents, and those of the fantastic Mirror team, we have a very bright future ahead of us."
