The Metropolitan Police said around 4,000 officers, supported by mounted units, drones, helicopters and police dogs, would be deployed to manage the demonstrations alongside security demands posed by the FA Cup final.

Authorities imposed strict conditions on the timing and routes of both marches in an effort to prevent clashes between rival groups. Police estimated the operation would cost approximately £4.5 million ($6 million) and warned they would adopt what they described as a “zero-tolerance approach” to disorder and hate speech violations.

For the first time, organizers of the demonstrations could face legal accountability if invited speakers breach Britain’s hate speech laws, the force said.Prime Minister Keir Starmer said on Friday that anyone attempting to “wreak havoc” or intimidate communities would face “the full force of the law.”

Speaking after visiting the Metropolitan Police operational control center, Starmer accused organizers of the far-right rally of “peddling hatred and division.”Starmer’s comments came days after his ruling Labour Party suffered setbacks in local elections, where hard-right Reform UK and nationalist parties made gains, intensifying pressure on his leadership.

Robinson, whose real name is Stephen Yaxley-Lennon, has become one of Britain’s most prominent anti-Islam activists, drawing large crowds through online campaigns focused on immigration, free speech and national identity issues.

Police estimate roughly 50,000 supporters could attend Robinson’s rally, while about 30,000 people are expected at the rival march organized by anti-racism campaigners and pro-Palestinian groups marking Nakba Day, which commemorates the displacement of Palestinians during the creation of Israel in 1948.

The anti-fascist group Stand Up to Racism merged its demonstration with the Nakba Day protest.Robinson urged supporters on social media to remain peaceful, avoid masks and limit alcohol consumption, while describing the gathering as a campaign to “Unite The Kingdom and the West.

”The Metropolitan Police said live facial recognition technology would be used for the first time during a protest operation in London. Officials also confirmed that 11 foreign far-right activists had been barred from entering Britain ahead of the rally.

Among those blocked was Valentina Gomez, whom the government described as using inflammatory rhetoric targeting Muslim communities.

Matthew Feldman, a specialist in far-right extremism at Liverpool Hope University, said some violent elements were likely to attend despite appeals for calm.

Taylor accused the government of reducing financial support for pensioners and older Australians, particularly through changes affecting private health insurance assistance.“At exactly the same time, they’ve ripped money away from pensioners and from older Australians with support for their private health insurance,” Taylor said while outlining the opposition’s policy priorities.

The opposition leader also vowed to confront what he described as “mass migration madness,” proposing a policy that would tie Australia’s annual migration intake to the pace of new housing construction.The announcement reflected growing political pressure over housing affordability, infrastructure strain and population growth, issues that have become central themes in national debate ahead of future elections.

Taylor’s remarks came days after the Coalition suffered a sharp electoral setback in the traditionally conservative seat of Farrer, where One Nation secured victory in last weekend’s vote.The Liberal candidate received just 12% of the primary vote, compared with the 43% previously secured in the electorate by former Liberal leader Sussan Ley a year earlier.

The result underscored growing fragmentation within Australia’s conservative voter base as One Nation gains support in regional and outer suburban areas amid concerns over migration, cost-of-living pressures and housing shortages.

The governing Labor Party has accused Taylor’s opposition of increasingly adopting policies associated with Hanson’s nationalist platform in an attempt to stem voter losses to the right-wing populist party.

One Nation has recently outperformed the Coalition in several major opinion polls, adding to pressure on the opposition to redefine its electoral strategy and policy agenda.

The case centers on Trump’s order, signed after his return to the White House, which would deny automatic U.S. citizenship to children born on American soil to parents residing illegally or temporarily in the country.

Federal courts previously halted the measure, citing the Citizenship Clause of the 14th Amendment, which grants citizenship to nearly all individuals born in the United States.

The administration argues that the 14th Amendment, ratified after the Civil War, was intended to secure citizenship rights for formerly enslaved people and does not extend to children of undocumented migrants or temporary visa holders.

In filings, Solicitor General John Sauer contended that eligibility for citizenship requires both birth in the United States and being “subject to the jurisdiction thereof,” a phrase the administration interprets narrowly.

Lower courts rejected that interpretation, relying on longstanding precedent, including the 1898 Supreme Court ruling in United States v. Wong Kim Ark, which affirmed citizenship for a U.S.-born individual of foreign parents.Legal scholars cited in the proceedings said the court’s historical reliance on precedent may weigh against the administration’s position.

Steven Schwinn, a law professor at the University of Illinois Chicago, said the court has traditionally looked to historical practice in constitutional interpretation.Trump confirmed he would attend the hearing, marking a rare instance of a sitting president observing oral arguments in a case involving their own administration.

While presidents have historically maintained distance from court proceedings, Trump has previously attended judicial ceremonies, including the 2017 investiture of Justice Neil Gorsuch.

The Supreme Court currently has a 6–3 conservative majority, with three justices appointed by Trump during his first term.The administration has argued that automatic citizenship for children of undocumented migrants acts as an incentive for illegal immigration and so-called “birth tourism.”

Opponents, including the American Civil Liberties Union, said the policy would undermine constitutional protections and create uncertainty over the citizenship status of millions of Americans.

The case follows a separate setback for Trump in February, when the Supreme Court struck down much of his global tariff policy. Trump criticized that ruling and renewed his attack on judicial decisions ahead of the current hearing.

A decision on the birthright citizenship case is expected by late June or early July.
