Britain's divorce from the E.U. is charging full steam ahead.

The road has been paved for phase two of negotiations to begin with the E.U. now demanding more clarity from the U.K. about the future relationship it wants.

British Prime Minister Theresa May admits there's still a while to go - but the talks are positive.

"I'm pleased that it has been agreed we should make rapid progress on an implementation period that will give certainty to businesses and individuals."
