George Osborne strongly supported China's involvement in sensitive sectors such as the Hinkley Point C nuclear power station. The then Home Secretary Theresa May had been unhappy about Osborne's "gung-ho" attitude to the Chinese, and had objected to the project. It has been delayed for final approval after May assumed the Prime Ministership. In 2015, May's political adviser Nick Timothy expressed his worry that China was effectively buying Britain's silence on allegations of Chinese human rights abuse, and criticised David Cameron and Osborne for "selling our national security to China" without rational concerns and "the Government seems intent on ignoring the evidence and presumably the advice of the security and intelligence agencies." He warned that the Chinese could use their role in the programme (designing and constructing nuclear reactors) to build weaknesses into computer systems which allow them to shut down Britain's energy production at will and "...no amount of trade and investment should justify allowing a hostile state easy access to the country's critical national infrastructure."
