LONDON (AP) — In a blow to the Scottish independence campaign, top financial groups including the Royal Bank of Scotland and Lloyds Banking Group say they will move their headquarters to England if Scots vote to break away from the United Kingdom.

RBS, which has been based in Scotland since 1727, said Thursday it has drawn up the contingency plans because of uncertainties that could hurt its business and customers if Scots approve independence in the Sept. 18 vote. Lloyds Banking Group, which owns Halifax and Bank of Scotland, also said it had plans to set up new “legal entities” in England if the Yes campaign succeeds.
