The centre was first announced in November 2015 by the Chancellor of the Exchequer, George Osborne. The existing Director General Cyber of GCHQ, Ciaran Martin, leads the new centre, and GCHQ's current Technical Director of Cyber Security, Dr Ian Levy, assumed the same role at the NCSC.[4] A detailed paper on the creation of the NCSC, including a description of its structure and future challenges, written by the then Director of GCHQ, Robert Hannigan, who is widely credited with establishing the centre, was published by the Royal United Services Institute in February 2019[5].
