Donald Trump's ban WILL apply to British citizens, the US embassy said
In an apparent contradiction to the UK Government's position, the US Embassy issued an 'Urgent Notice' on its website.
It tells UK citizens who share dual nationality with one of seven mainly-Muslim countries covered by the restrictions not to apply for visas, meaning individuals such as Tory MP Nadhim Zahawi could yet be affected.
The notice states: "Per U.S. Presidential Executive Order signed on January 27, 2017, visa issuance to aliens from the countries of Iraq, Iran, Libya, Somalia, Sudan, Syria and Yemen has been suspended effective immediately until further notification.
"If you are a national, or dual national, of one of these countries, please do not schedule a visa appointment or pay any visa fees at this time.
"If you already have an appointment scheduled, please DO NOT ATTEND your appointment as we will not be able to proceed with your visa interview.
"Please note that certain travel for official governmental purposes, related to official business at or on behalf of designated international organizations, on behalf of the North Atlantic Treaty Organization, or by certain officials is not subject to this suspension."
We will not be able to proceed with your visa interview.
Last night, the Foreign Office had insisted British dual nationals would not be affected by the ban after Foreign Secretary Boris Johnson won assurances in a phone call with President Trump's son-in-law Jared Kushner yesterday.
Foreign Office sources told Express.co.uk they still believed British nationals were exempt from the visa ban but were working to clarify the US Embassy's new advice.
It was suggested the contradiction could be due to confusion among American officials over the implementation of President Trump's executive order.
More than one million Britons have signed a petition calling for President Trump's state visit to the UK to be cancelled following the introduction of his ban.
Mr Johnson is due to make a statement to MPs this afternoon.
