One of Sky News's longest-serving correspondents is to leave after more than 10 years with the channel, as it announces 17 job cuts.
Sky is scrapping evening news shows World News Tonight, presented by James Rubin, and The Sky Report, presented by Julie Etchingham.
Rubin will continue to present special programmes on international affairs.
Head of Sky News Nick Pollard said: "The journalists on both World News Tonight and The Sky Report have worked incredibly hard to produce some outstanding and original journalism.
"One of the aims of the schedule change is to integrate some of the strengths within our general programming, rather than focusing that effort solely on two specific peak-time shows."
The news of the schedule changes comes less than a month after Pollard, who is thought to have argued against the cuts, announced his departure after 10 years.
Chater joined Sky in 1993, when he opened its Moscow bureau.
His exit is not believed to be linked to the current job cuts.
A new show is to be developed for the 8pm slot left vacant by The Sky Report which will be, according to the station, "news driven and interactive".
The new show will be presented by Martin Stanford.
