time used up, the bill could proceed no further through Parliament. European reform from 2021 In 2018, after conducting a public survey, the European Commission proposed to put an end to seasonal clock changes in the European Union with effect from 2019. The European Parliament supported this proposal; however, , the proposal was still awaiting approval from the Council of the European Union, without which it will not come into force. If the proposal is ultimately approved, implementation will be deferred. Each member state will choose whether to remain on its current summer time, in which case the last transition would be on the last Sunday of March in the year of implementation, or its current winter time, which would take permanent effect from the last Sunday of October. Although the United Kingdom left the EU before any new directive became effective, EU rules continued to apply during the transition period. Thereafter, the UK can choose to make its own arrangements. If the UK were thus to continue observing summer and winter time, Northern Ireland would have a one-hour time difference for half the year either with the Republic of Ireland or with the rest of the UK. , the UK Government had "no plans" to end daylight saving. In July 2019, the House of Lords EU Internal Market Sub-Committee launched a new inquiry into the implications for the UK of the European changes, to "explore what preparations the Government needs to make and what factors should inform the UK's response."
