The Telegraph editor-in-chief and chief content officer Jason Seiken has stepped down after less than two years in the role.
Seiken joined the Daily Telegraph from US public service broadcaster PBS in 2013.
His departure was announced in an email to staff this morning, in which he said: "I’m proud of how the Telegraph has become a digital leader, and I’m gratified that the Telegraph has seen such a large growth in its digital audience.
“The company has a great future and will continue to thrive. I wish all my colleagues at the Telegraph the very best for the future.”
Murdoch MacLennan, Telegraph Media Group chief executive, said: "We completely understand Jason’s regrettable decision to move on to new opportunities now that he has completed his work here.
“He has been a much valued colleague, providing a great deal of input into identifying future strategy for the Telegraph Media Group to ensure we remain a world-class and commercially successful media organisation. We wish him well.”
Chris Evans, the Daily Telegraph's 'Monday-to-Friday' editor, will remain in his post. He is also director of content, overseeing all digital and print output.
The Telegraph also confirmed that former news editor Matthew Bayley is returning from Sky News as head of content strategy, and Jane Bruton is arriving from Grazia as director of lifestyle.
