The pound tumbled against the dollar at the end of the week. The British currency responded to negative expectations and recorded serious loss. As a result, two key levels at 1.2505 and 1.2428 were overcomed, and meanwhile the pair made the third test of the support at 1.2366. If the downward momentum continues in the future, it will be breached. After correction upward, the pair closed the week at 1.2487.
