Brexit: Theresa May says agreement is "important step" on the road to Brexit

British Prime Minster Theresa May said Friday's agreement was an "important step on the road" to delivering Brexit.

She praised "commitment and perseverance on both sides" and said she was pleased there would be "rapid progress" on work on an "implementation period".

This is expected to last for up to two years after the UK's exit in March 2019.
