Guy Eaton has joined investigative journalism website Exaro as associate editor.
Eaton was the Daily Mail's associate features editor from 1998 before joining the Evening Standard in 2002 to head its features department.
As assistant editor of the Standard until 2009 he was also responsible for investigations into politics, business, crime and foreign reporting assignments.
He began working for Exaro in March as a freelance contributor and commissioning editor and in his new role will report to editor-in-chief Mark Watts and help oversee Exaro's major investigative projects from May 2012.
Watts said: 'I am delighted that Guy is joining our growing team of more than 30 journalists. The rise of online investigative journalism, particularly as newspapers stop investing in it, was evident this week with Exaro's latest revelations on the Whitehall tax row."
Exaro appointed Keith Perry, former night news editor at the News of the World and ex-Sunday Express news editor, as associate editor in January.
Another recent addition to the Exaro editorial team is Richard Wachman, who was City editor of The Observer for 11 years until March. He started working for Exaro in April.
This week an Exaro investigation revealed how more than 2,000 UK public officials are paid â€˜off payroll', allowing them to minimise their tax payments. For the second time this year Exaro teamed up with BBC2's Newsnight to break the exclusive.
Meanwhile, Exaro is looking to recruit a commissioning editor to oversee its business channel.
