The Sunday People editor, James Scott, has become the first serving newspaper editor arrested over alleged phone hacking, relating to his time at the Sunday Mirror a decade ago.

Scott was one of four former Sunday Mirror senior journalists arrested in dawn raids on Thursday on suspicion of conspiracy to intercept voicemail messages. Tina Weaver, the ex-Sunday Mirror editor who is seven months pregnant, was also arrested on Thursday morning.
