Talk the Brexit vote could be delayed
There's a completely unsourced (and very likely untrue) rumour that the Brexit vote could be delayed because of the murder of UK MP Jo Cox today.
There was some talk that the person who did it yelled "Britain first" or something like that before he attacked her but that account has been disputed.
At times like this it's easy to spread rumours and the best rumours have a small ring of believability. Cameron would certainly like a reason to call the whole thing off as his little gamble looks like it could be the end of his political career.
Tough to say how much of the GBP bounce is related to the rumour and how much is related to flows and a squeeze.
