Ireland's prime minister met European Council President Donald Tusk in New York on Monday for 45 minutes to take stock of the latest Brexit developments.
A spokesman for Leo Varadkar said the prime minister and Tusk agreed that they want a deal but they have not yet seen proposals from Britain that achieve the objectives of the backstop.
"They also agreed that time is very short if there is to be a positive outcome at the Europe Council," the spokesman said.
