Question to the Ministry of Defence:

To ask His Majesty's Government whether the underlying environmental monitoring data from Christmas Island relating to the 1957–1958 nuclear tests has ever been disclosed to the courts in litigation brought by nuclear test veterans against the Ministry of Defence.

The Government is deeply grateful to all those who participated in the UK nuclear testing programme. We recognise their service and the huge contribution they made to the UK’s security. This Government has reset the relationship with nuclear test veterans and the organisations that support them. We remain committed to listening to their concerns and working collaboratively to address them.

During a House of Commons debate last week, the Minister for Veterans and People reiterated the government’s commitment to maximum transparency and made a commitment to undertake work to fully understand the implications of the 2014 report and its handling, and to take action if necessary (Hansard, HC Deb, 25 March 2026, vol 783, col 377).
