Tusk tweeted on Tuesday that he will urge the other 27 EU nations to approve Britain's delay, Associated Press reports.
Britain has sought a three-month delay until the end of January 2020. That was done after Parliament passed a law forcing Prime Minister Boris Johnson to seek the delay.
Jean-Claude Juncker and Donald Tusk have made statements on Brexit's conclusions at last week's European Council, the European Union reported. They were also joined by Manfred Weber, with statements on Turkey and its Syrian operation. The issue of rejection of negotiations with Northern Macedonia and Albania was also addressed.
