Scotland is pushing stronger for another referendum
As we know, Scotland voted to remain in the EU by more than 60%, which is a considerable percentage. But England voted to leave the EU and being about 10 times bigger in terms of population the leave camp won. Scotland is not liking this at all. The Scottish feel a lot more connected to Europe than the English for a number of reasons.
Now Scotland can´t accept the outcome of the Brexit referendum for a number of reasons, but the two main reasons are because they really don´t want to leave the EU and they now feel that they don´t matter since their voice is not heard. That makes a perfect combination of reasons to leave the UK.
The voices for a Scottish referendum are getting stronger and if it happens I´m pretty sure Scotland will vote to get out of the UK. That´s another reason for the Pound to hit rock bottom besides Brexit itself. GBP/USD is at multiple year lows so there isn´t a support level nearby.
