On Tuesday, September 24, the British Pound appreciated 75 pips or 0.60% against the US Dollar. Note the British Pound extended gains against other major currencies as well.
The reason for the advance was a decision by the United Kingdom Supreme Court on the Parliament suspension. The Court ruled that the Prime Minister Boris Johnson's order to suspend the Parliament in the run-up to Brexit was unlawful.
Opposition leaders have already demanded that the Prime Minister should resign now, as he deceived Queen Elizabeth, who officially suspended the Parliament on his advice.
