Precious metals are a hedge against uncertainty. With the current Brexit situation and the wobble in the stock market, you want to be acquiring precious metals, not selling them. You have a very backwards and upside-down view of the world if you are "spooked out" of a safehaven asset class to jump back into fiat. Sadly, this is how most of the population thinks, and that's why we're heading ever nearer the financial cliff. 

Brexit has the potential to send Sterling down - this would mean it would cost you more GBP to buy gold.
As @JCRJM says you don't properly understand gold as an investment and hedge yet. Do not give up - keep reading and learning about the subject.
