Donald Tusk will meet Boris Johnson in France on Sunday, ONA reports citing Evening Standard.
The European Council President will hold a face-to-face meeting with the British Prime Minister at 10:30am on the sidelines of a G7 summit in France, Mr Tusk's schedule showed on Wednesday.
It comes after Mr Johnson wrote a letter to Mr Tusk earlier this week, calling for the backstop to be scrapped.
Mr Johnson reiterated his opposition to the so-called insurance policy, saying he will not support any withdrawal agreement that includes it.
Responding, Mr Tusk suggested Downing Street secretly wanted to bring back a hard border with Ireland. He also said Britain was offering no “realistic” solution.
"The backstop is an insurance to avoid a hard border on the island of Ireland unless and until an alternative is found," Tusk said in a Tweet, responding to the letter on Monday.
"Those against the backstop and not proposing realistic alternatives in fact support re-establishing a border. Even if they do not admit it."
