The Sun’s assistant editor Paul Hudson is relocating to Dublin to take over the paper’s Irish edition, a move that sees the departure of Irish editor Mike McNiffe after seven years.

London-based assistant design editor Nathan Brandon is also relocating to Dublin as the company looks to make “significant changes” to the Irish edition.

Sun editor Dominic Mohan emailed staff last week saying publishers News International had completed an “extensive review” of the Irish Sun to “ensure it has a successful future in a difficult economy”.
