The situation you described indicates a potential volatile period in Britain. The occurrence of riots suggests there are deep social and political issues that need addressing.
The “far right” usually refers to the extreme political right, which is typically associated with nationalist, anti-immigration, and sometimes racist ideologies. Their lingering presence may be a result of perceived threats to their political or cultural identity. This could potentially lead to more conflict if their stance further polarizes society.
The government and concerned agencies should aim at maintaining peace, engaging with all communities, and taking steps to address the root causes of the unrest. This could include increased support for social services, police reforms if necessary, and consistent communication from leaders to bring a sense of unity and calm.
