A dispute between business and the government over its tax treatment of multinationals is set to deepen this week when WPP, the world's second-largest advertising agency, announces plans to shift its British headquarters to Ireland.
WPP is expected to say it is moving its tax domicile from the UK because of the threat of a markedly higher corporation tax bill. WPP would be the latest UK-based group to shift its domicile - or to consider doing so - because of complaints about the tax system's waning competitiveness.
