What makes a crowd of 15,000 chant the slogan of “Stop the boats” in the heart of London? Is it fear, anger, or the echo of a nation struggling to hold on to a sense of itself? The answer is harsher, the sense of losing their identity. This week, London witnessed a wave of anti-immigration protests—unearthing the underlying tensions in Britain. In central London, demonstrators united under the slogan of “Unite the Kingdom”, a call showing the polarizing debate of immigration. Organized and amplified by the far-right activist Tommy Robinson, the protesters divulged the deeper anxieties over migration and Britain’s long-standing relationship with newcomers.
