Missing from the left

Only 4 of the 23 outlets with a published leaning rating that ran this story are rated left.

A reader who follows the left would not have seen this. We report the absence rather than explain it: outlets choose what to cover for many reasons, and we have no evidence about which one applies here.

Anti-migrant protesters and counter-demonstrators gathered in Portsmouth on Saturday. Hampshire Police had a significant presence in the city centre. The force warned that individuals wearing face coverings could be arrested under the Crime and Policing Act. No one was seen wearing masks at the demonstrations following these warnings.

The anti-migrant group marched to Guildhall Square, with banners including "We've had enough stop the boats" and "Stand up, speak out, stop the grooming gangs". Chants of "stop the boats" were heard. Counter-demonstrators, holding signs such as "RNLI are heroes, no-one is illegal" and "Hate has no place in Pompey", gathered in a neighbouring car park. Chants from this group included "Scapegoat migrants no way, blame the rich and make them pay" and "refugees are welcome here".

The two groups assembled to face each other on opposite sides of Guildhall Square, with some shouting. The Evening Standard reported that the Stand Up To Racism side chanted "stop the hate" while the anti-immigration side booed. Chants about deportation were heard from the anti-immigration protesters.

Disagreement on arrests

LBC reported that a 76-year-old man was arrested over face covering at the anti-immigration protest. The Evening Standard reported that the first man charged over last week's anti-migrant demonstration in Portsmouth, Del Leon Somerville, 42, appeared before Portsmouth Magistrates’ Court charged with violent disorder and assaulting a police constable. Assistant Chief Constable Tony Rowlinson stated Somerville’s arrest was the "first of what we fully anticipate to be a number of arrests".

What the coverage left out

None of the centre or right-rated reports mentioned the specific details of the previous anti-migrant demonstration in Dover, beyond condemnation of masked men blocking roads. The centre-rated Evening Standard mentioned the events in Dover and Portsmouth last weekend in relation to the Home Secretary's meeting, but did not provide details of the previous Portsmouth demonstration beyond the arrest.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

4 rated outlets

  • The Independent reported that police in Portsmouth warned demonstrators that face‑covering powers could be used, and that a 76‑year‑old man was arrested on suspicion of concealing his identity. The article noted the use of the Crime and Policing Act, cited the police and crime commissioner’s comment that most protesters were peaceful, and mentioned a Home Secretary meeting.
  • The Independent quoted PCC Donna Jones saying the protest was largely peaceful and that the new law required faces to be uncovered, and quoted Home Secretary Shabana Mahmood on dealing with far‑right groups. It also reproduced a protester’s chant of “stop the boats” and described banners from both anti‑immigration and Stand Up To Racism groups.
  • The Independent’s digest only noted the arrest for concealing identity and omitted details about the counter‑demonstration, RNLI involvement, and the police commissioner’s remarks on proportional use of powers. No cost figures or broader political analysis appeared in either the full report or the digest.

  • The centre-rated reports led on the rival demonstrations in Portsmouth. The Evening Standard's full report detailed the police warnings about face coverings and potential arrests under the Crime and Policing Act. It described the banners and chants of both groups, noting the "stop the boats" slogan from anti-migrant protesters and "refugees are welcome here" from counter-demonstrators. This report also detailed the arrest and charges against Del Leon Somerville in relation to a previous demonstration and quoted Assistant Chief Constable Tony Rowlinson. The Home Secretary Shabana Mahmood's meeting with police to discuss readiness in dealing with far-right groups was also a focus, as were the condemned scenes of masked men blocking roads in Dover. Sky News UK's digest noted that police faced a challenge as scuffles broke out and around 100 anti-migration demonstrators "splintered off" to chase counter-protesters.

  • The right-rated reports focused on the protests and related arrests. Protothema's digest stated that police set up a security perimeter to prevent the two gatherings from coming into contact. LBC's digest reported that a 76-year-old man was arrested over a face covering at the Portsmouth anti-immigration protest.

Questions about this coverage

How did the left and right cover Portsmouth protests: Anti-migrant and counter-demonstrators clash?
Of the 23 outlets on this story carrying a published leaning rating, 17% are rated left, 39% are rated centre, 44% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 49. The sections above set out what each side emphasised, in its own terms.
Is Portsmouth protests: Anti-migrant and counter-demonstrators clash left or right?
Neither side dominates it. Of the 23 rated outlets on this story, 17% are rated left, 39% are rated centre, 44% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Portsmouth protests: Anti-migrant and counter-demonstrators clash biased?
Portsmouth protests: Anti-migrant and counter-demonstrators clash is one event reported by 49 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting Portsmouth protests: Anti-migrant and counter-demonstrators clash?
