EU President Donald Tusk on Thursday confirmed the bloc would hold a special summit to seal the hard-fought Brexit agreement with Britain on November 25.

"If nothing extraordinary happens, we will hold a European Council meeting in order to finalise and formalise the Brexit agreement. It will take place on Sunday the 25th of November at 9:30 am," Tusk said, a day after the 585-page withdrawal agreement was approved by the British cabinet.
