A non binding-referendum was held on 23 June 2016 to decide whether the UK should leave the EU (Brexit) or remain a member of it. With a majority of voters, 52%, in favour of Brexit, the British government has promised to leave the EU. It is not clear when the UK will effectively leave the EU, this process being unprecedented. Hence, it has not been clarified if these MEPs will remain in their seats until Brexit, if it happened before the subsequent European Parliament election, or if they would remain as MEPs until this Parliament is dissolved in 2019. In any event, if the UK had left the EU before the election of the 9th European Parliament, the mandate of the listed members would be ended on that date, regardless of the process of the Brexit negotiations.
