Britain's Supreme Court unanimously found that the British government had violated its authority by closing the parliament. The 11 judges found that there was no good reason to advise the Queen to suspend the parliament, and since the government's evidence was weak, British Prime Minister Boris Johnson's decision was illegal. "As a result, the decision is still null and void," said Chief Justice Lady Hill. Accordingly, House Speaker John Birko confirmed that the parliament will be convened from 11:30 am Wednesday. This positive development will provide support to prevent Brexit without a deal, and thus hampered Prime Minister Johnson's ability to get Britain out of the EU at any cost on Oct. 31. This development did not provide strong support for the GBP / USD pair which moved towards 1.2502 just before settling around 1.2460 at the time of writing. Investors seem to want to know the reaction of the British parliament when it returns.

If the optimism towards the Brexit continues, the pair may gain additional momentum towards the 1.2590, 1.2665 and 1.2720 resistance levels respectively. On the downside, the closest support levels for the pair are currently 1.2390, 1.2300 and 1.2245 and the last level is the culmination of the bearish trend again, and ending the current optimism. Brexit will remain the most influential factor on the pair's direction in the coming period.
