The UK Brexit Secretary Davis is on the wires now, via Reuters, testifying to the Brexit parliamentary committee.

Key Headlines:

Government has no overall impact assessment on Brexit.

Impact assessment on individual sectors of the economy not necessary at this point.

Usefulness of a detailed impact assessment is zero.

At some stage, we can at best try to quantify the different negotiating outcomes for Brexit.

Will assess the impact of various Brexit outcomes closer to negotiation timetable.
