The Home Secretary has ordered immigration officials to issue a full six-month business visa to dissident Chinese artist Ai Weiwei, reversing a decision to only allow him into the country for less than three weeks.
Theresa May reviewed the decision after human rights experts voiced anger over the decision when the artist, an outspoken critic of the Chinese government, was denied the full visa.
In a letter posted to his Weiwei's Instagram account, officials said they refused him a longer stay as he he had not declared a previous "criminal conviction" - despite supporters denying he had ever even been charged.
He was secretly detained, his passport confiscated and later fined for alleged unpaid taxes, though his supporters argued this was merely a politically-motivated punishment for his views.
His passport was only returned last week, and he had hoped to visit Britain in the autumn to coincide with an exhibition of his work at the London Royal Academy of Arts.
A Home Office spokesman said Ms May was not consulted on the original decision, adding:
A fault which left RBS, NatWest and Ulster Bank customers unable to login to their online banking this morning has been fixed, RBS has said.
The cause of the problem, which lasted around 50 minutes, was still being investigated.
