EU's Tusk says 'most difficult challenge' ahead in Brexit talks

BRUSSELS: EU President Donald Tusk warned that talks on a post-Brexit trade deal and transition period would be even more difficult than a hard-won agreement on divorce terms that was sealed on Friday.

"Let us remember that the most difficult challenge is still ahead. We all know that breaking up is hard but breaking up and building a new relation is much harder," Tusk said, reading a statement.
