Ukrainian President Petro Poroshenko has postponed his visit to the United Kingdom, which was originally planned for May 11-12, the presidential press service reports.

"Ukrainian President Petro Poroshenko's working visit to the United Kingdom, which was announced for May 11-12, has been postponed, due to the situation surrounding the election of a new prosecutor general, and the parliament's non-passage of bills essential for continuing cooperation with the IMF," the press service said on Tuesday evening.
