Channel 4 News economics editor Faisal Islam is to succeed Adam Boulton as Sky News political editor.
Boulton is stepping down after 25 years to take up a presenting role. Islam will start his new job later in the year.
Islam is a former economics correspondent for The Observer.
Head of Sky News John Ryley said: "The political editor is one of the most important and demanding roles at Sky News. We have a long history of challenging the way politics is reported in the UK and I know Faisal is keen to continue this, I am confident he will rise to the challenge. He is an impressive journalist and will make a very strong addition to our first class political team in Westminster."
Islam said: "I'm honoured to be joining Sky at an extraordinary time in British politics. This is a great opportunity journalistically and technologically and I am delighted I will be part of a team with such a strong reputation for breaking news and innovation.
"I've had a fantastic decade at Channel 4 News and I will miss all my talented colleagues and the world of economics. The opportunity at Sky to help transform political broadcasting is an exciting challenge that I could not resist."
It has been reported that Adam Boulton was paid more than £400,000 a year by Sky News.
