Market remembers what the fundamentals look like through the Brexit fog
GDP revisions are not usually a big market mover unless it's a big mover itself. The pound has fallen off its perch above 1.4700 to 1.4677, briefly slipping below intraday support at 1.4685/90.

1.4660 is where we should see support if we drop under 1.4680, followed by 1.4635/40.
There's nothing horrific in the GDP data, there's nothing amazing in it either. The market has just had a reminder that whatever happens with the Brexit vote, there's still a lot of work to be done on the economy.
