Foreign Secretary Boris Johnson said:
I am deeply saddened to hear that Liu Xiaobo has passed away. He was a Nobel Peace Prize Laureate and a lifelong campaigner for democracy, human rights and peace. His death is a huge loss and our hearts go out to his wife Liu Xia, his family, and his many friends and supporters.
Liu Xiaobo should have been allowed to choose his own medical treatment overseas, which the Chinese authorities repeatedly denied him. This was wrong and I now urge them to lift all restrictions on his widow, Liu Xia.
