In the published draft conclusions of their meeting, the EU 27 say:
1. The European Council takes note of the letter of Prime Minister May of 20 March 2019.
2. In response, the European Council approves the Instrument relating to the Withdrawal Agreement and the Joint Statement supplementing the Political Declaration agreed beteween the European Commission and the government of the United Kingdom in Strasbourg on 11 March 2019.
3. The European Council commits to agreeing, before 29 March 2019, to an extension until 22 May 2019, provided the Withdrawal Agreement is approved by the House of Commons next. Given that the United Kingdom does not intend to hold elections to the European Parliament, no extension is possible beyond that date.
The last sentence is the interesting one.
