In 2002 she returned to London as City news editor and was appointed media business editor in 2004.
Media Guardian editor-in-chief of Janine Gibson said: ‘This is one of the most prestigious and challenging media jobs in the business, Matt Wells will be a hard act to follow but we are delighted to have secured Jane who will bring a great blend of city and media experience to the role. ‘
Martinson, who will begin her role in January 2008, replaces Matt Wells who is to become head of audio.
