Additional easing from the Bank of England is not a sure-fire thing anymore, and GBPUSD rallied to the post-referendum range's top.
This is in line of what I've been saying for a long time - Brexit referendum and eventual Exit will not be THAT bad.
I doubt the GBPUSD is ready to rally above the trading range just on the accumulated positive newsflow - more will be needed for that. I'd pocket profits from possible GBP-longs, possibly even go short at current levels.
There will be better opportunities to go long GBP in the near future, I guess.
