I can assure my hon. Friend that he meant March 2019. In answer also to the hon. Member for Leeds North West (Alex Sobel), I would like to assure the House that the UK and the EU have
reached agreement on the terms of an implementation period that will run from 30 March 2019 until the end of 2020. The existing Euratom treaty arrangements will continue during this period and businesses will be able to continue to trade on the same terms as now. As part of this, the UK and the EU agreed that for the duration of the implementation period the EU’s international agreements will continue to apply to the UK. This will include Euratom’s existing nuclear co-operation agreements with the USA, Canada, Australia and Japan.
