Daily Telegraph deputy news editor Thomas Penny has become the latest journalist from the pre-Barclay brothers regime at the paper to leave.
Penny has resigned from the Telegraph news desk where he worked alongside executive head of news, Tony Gallagher, and the news editor, Chris Evans - two recent hirings from the Daily Mail.
Their recruitments followed the arrival of deputy editor Ian MacGregor, from the London Evening Standard, although he had previously worked at the Mail.
Penny's departure comes just days after Celia Hall, the Telegraph's medical editor, announced she was leaving the paper after more than 11 years to go into PR.
Other long-serving Daily Telegraph journalists who have left in recent months include David Lucas, the night editor, and former deputy editor, Neil Darbyshire.
An insider said: "This is yet another opportunity to bring someone in from the Mail to take over our management."
