Another key part of information - I suggest keeping an eye on UJ and using that as a measure for GBP direction, it has traded with a VERY strict range of 30 pips.
The price action of GBP pairs is somewhat compromised by its high volatility (e.g. price action is so volatile it is hard to calll tops) so instead use UJ which is trading with discipline.
1. When UJ falls, this CONFIRMS GBP downside - as it shows a tightening of risk appetite, Lower GBP is the risk-off play.
2. When UJ rises, this CONFIRMS GBP upside - as bets on GBP upside is the more risky move given the absolute event uncertainty, thus JPY weakening confirms the market wants to take more risk with GBP upside plays
