Britain’s Prime Minister Theresa May on Friday said there was no economic case for breaking up the United Kingdom, in a speech attacking Scottish nationalists for being “obsessed” with independence.

Since 2016 Brexit vote, Scottish National Party leader and Scottish First Minister Nicola Sturgeon had repeatedly said she could push for a new independence referendum if the country was forced into a clean break with the bloc.

“The economic case for the union has never been stronger.

“There is no economic case for breaking up the UK or of loosening the ties which bind us together,’’ May told her Conservative Party’s Scottish conference in Glasgow.

May also said that no decisions currently taken by the Scottish parliament would be removed from it when Britain leaves the EU.
