BBC Breakfast co-host Naga Munchetty is set to leave the programme after 17 years, the BBC has confirmed.
She will instead join Radio 5 Live's breakfast programme full-time, an opportunity she said was "too good to pass up".
Munchetty joined the Breakfast programme as a finance reporter and has been a main host for 12 years.
"It has been a privilege to be part of the BBC Breakfast TV team for the past 17 years, working alongside an incredibly talented and hard-working group of journalists who are not only outstanding colleagues but also great friends," she said in a statement.
"Presenting a flagship programme on 5 Live is an opportunity that was simply too good to pass up.
"It will take a huge amount of work and require 100% of my focus and energy, and I'm really looking forward to throwing myself into the role."
She currently presents the Breakfast show for part of the week plus 5 Live's mid-morning programme on some week days.
From December, she will present 5 Live Breakfast five days a week.
