1. Summary of the results

Based on the analyses provided, the largest British protest in the last 5 years was a pro-Palestinian rally that drew an estimated 300,000 attendees [1] [2]. This significantly surpassed other major demonstrations during this period.

The second-largest protest was the 'Unite the Kingdom' rally organized by far-right activist Tommy Robinson, which had varying attendance estimates ranging from 110,000 to 150,000 people [3] [1] [4] [5] [2] [6] [7]. Multiple sources consistently report this event as drawing between these figures, with some sources noting it exceeded organizers' expectations [4]. The rally was characterized as an anti-immigration demonstration and resulted in clashes with counter-protesters and injuries to police officers [1] [4].

A significantly smaller protest mentioned in the analyses was one against Trump's state visit, which drew approximately 5,000 attendees [8]. This demonstration was specifically related to opposition to Donald Trump's second UK state visit but represented a much smaller scale of public participation compared to the other events.

The sources indicate that the Tommy Robinson rally was notable not just for its size but also for the violence that occurred, with multiple references to police injuries and clashes between different groups [4] [1]. Counter-protests also took place simultaneously, with one source estimating about 5,000 counter-protesters [7].

2. Missing context/alternative viewpoints

The analyses reveal several important contextual elements that provide a more complete picture of British protest activity. The pro-Palestinian rally mentioned as having 300,000 attendees occurred in November 2023 [2], placing it within the specified five-year timeframe and establishing it as the clear leader in terms of attendance figures.

The characterization of the Tommy Robinson event varies across sources, with some describing it as a "far-right rally against immigration" [1] while others frame it more neutrally as the "Unite the Kingdom rally" [6] [4]. This difference in framing suggests varying editorial perspectives on how to categorize the political nature of the demonstration.

The presence of counter-protests adds another dimension to understanding these events [7]. The fact that the Tommy Robinson rally generated significant opposition demonstrates the polarizing nature of the issues being protested, which is important context for understanding the broader social and political climate surrounding these demonstrations.

Some sources note that the Tommy Robinson rally was described as potentially "the largest anti-immigration rally held in UK history" [5], though this claim appears to focus specifically on anti-immigration protests rather than all protests generally. This distinction is important for understanding the specific nature of different types of demonstrations.

3. Potential misinformation/bias in the original statement

The original question itself appears neutral and factual, simply asking for information about protest attendance figures. However, the framing could potentially lead to incomplete understanding if readers don't consider the political context and nature of these demonstrations.

The analyses reveal potential bias in how different sources characterize the same events. The Tommy Robinson rally is variously described as "far-right," "anti-immigration," or more neutrally as "Unite the Kingdom," suggesting that source selection and framing can significantly influence public perception of these events [3] [1] [5].

The omission of the pro-Palestinian rally from some analyses while focusing heavily on the Tommy Robinson event could create a skewed impression of which protests actually had the largest attendance [8] [3]. Only two sources mention the 300,000-person pro-Palestinian demonstration [1] [2], despite it being the largest protest according to the available data.

Additionally, the variation in attendance estimates for the Tommy Robinson rally (ranging from 110,000 to 150,000) demonstrates how crowd size estimates can vary significantly between sources [3] [4] [5], potentially reflecting different methodologies or biases in reporting. This uncertainty in crowd counting is a common issue in protest coverage that can be exploited to either inflate or diminish the perceived significance of demonstrations.
