According to his spokesperson, European Commission President Jean-Claude Juncker warned UK Prime Minister Theresa May in a phone call that short Brexit extension has to be complete before May 23.
.@JunckerEU thinks it is good that @theresa_may sets out her thoughts ahead of #EUCO; warned her in phone call against including a date for the extension that is after #EUelections2019. #Brexit has to be complete before 23 May – otherwise #EUelections2019 have to be held in UK.

The spokesman also later said:
“President Juncker said to the prime minister that he thinks it’s a good idea she sets out her thoughts to the leaders ahead of the EU Council.
However, the president has clearly warned the prime minister against including a date for the extension that will be after the European parliament elections. That’s why he repeated in this call his advice, which he set out in his letter on March 11, that the withdrawal has to be complete before May 23, otherwise we risk facing institutional difficulties and legal uncertainty, given the European elections date.
European elections have to be held if the extension date is beyond May 23. This is the position of the commission and this is what the president informed the prime minister again.”
