Sky News is opening a new US West Coast bureau in Los Angeles next month.
The new office is being set up by US correspondent Greg Milam, who is moving from his current base in Washington DC but will continue to cover stories across the US.
Amanda Walker, formerly Russia correspondent, has taken on the role of US correspondent, replacing Milam and joining Dominic Waghorn in Washington DC.
Last year Walker covered the Russian Presidential election, the trial and imprisonment of punk band Pussy Riot and the flash floods which killed 150 people in the south of the country.
Walker also reported on Superstorm Sandy and the US elections in Florida. She will be replaced as Russia correspondent by Katie Stallard, who leaves her current role as media and technology correspondent in London
Stallard, who will now be based in Moscow, is to be replaced by news correspondent Niall Paterson.
Sky News head of international Sarah Whitehead said: “I’m excited at the prospect of having four correspondents covering the US, coast to coast.
“Having a presence on the West Coast will enable us to tell stories from across America with all time zones covered.”
Milam moves to LA in February.
