Some 1,427 people crossed the Channel in small boats in the past seven days, according to Home Office data.
Last Sunday, Aug 11, saw the highest number of crossings in a day since the Labour leader entered No 10, with 703 people making the journey.
The figures showed that 492 people made the crossing in nine boats on Saturday Aug 17 - the second highest daily number since Labour took power.
Some 107 arrived on Wednesday and 125 on Monday.
The third highest daily number came on July 15, within a week of Labour taking power, with 427 people crossing in nine boats.
The total crossing in the past seven days takes the provisional total for the year so far to 19,066.
Comment: It seems likely that this number is much higher; in 2022, 1,000 migrants a day were officially recorded as arriving during the summer, with at least 40,000 arriving by boat that year. The government has also admitted that it has lost track of at least 17,000.
Since Labour took office there have been a total 5,491 crossings in small boats, with 717 in the party's first week of power; 1,426 in the second week; 484 in the third week; 829 in the fourth week; 608 in the fifth week; and the past week's total.
The highest number of arrivals recorded in a single day so far this year was 882 on June 18, with the second highest of 711 on May 1 - both under the previous Conservative government.
The Government has indicated that it expects to see more crossings as traffickers take advantage of the summer's good weather over the Channel.
The Conservatives have condemned Labour's decision to ditch the previous government's plan to deport migrants to Rwanda, which they claimed would deter Channel crossings.
Comment: Note that other European countries, such as Hungary, Poland, Belarus, and Russia, aren't struggling with mass migration, because they simply don't tolerate it. And they don't need a 'Rwanda plan' to deal with it.
Japan, also an island nation, doesn't seem to have any real problem handling illegal migrants, either: Japan granted refugee status to 'record high' 303 asylum-seekers in 2023
James Cleverly, the shadow home secretary and a Tory leadership candidate, said: "When Labour ditched our deterrent they sent a dangerous signal to the people smugglers that they were not willing to take the tough action necessary to control our borders, and the smugglers are reaping the benefits.
"And over a month later, they still have not appointed anyone to run their phantom Border Command.
"This new Government must urgently take action to get a grip on these ever rising crossing numbers."
Mel Stride, another Tory leadership hopeful, said: "An effective illegal migration policy has to involve a strong deterrent. We are seeing small boat crossings increase significantly after just a few weeks of a Labour government, showing that going soft on deterrence does not work.
"Labour's approach means more people risking their lives and makes our country less secure."
Labour promised ahead of the election to "smash the gangs" bringing migrants across the Channel by creating a new Border Security Command.
Officers will be granted new powers under the Counter Terrorism Act to allow them to conduct stop and searches at the border, carry out financial investigations and issue search and seizure warrants targeting organised immigration crime.
Comment: Why would illegal migration be dealt with under the 'Counter Terrorism Act'?
Sir Keir has also announced £84 million of funding for African and Middle Eastern countries in an attempt to tackle the migration crisis "at source".
Comment: This is the same government that's supplying billions of dollars of assistance and weapons to the genociders in Israel, who are trying to provoke a Middle East conflagration.
He has said the money will go towards health and education initiatives and humanitarian support to address the underlying causes that lead people to flee their homes in the first place.
A Home Office spokesman said: "We all want to see an end to dangerous small boat crossings, which are undermining border security and putting lives at risk.
"The new Government is taking steps to boost our border security, setting up a new Border Security Command which will bring together our intelligence and enforcement agencies, equipped with new counter-terror-style powers and hundreds of personnel stationed in the UK and overseas, to smash the criminal smuggling gangs making millions in profit."
Comment: If successive UK governments - both Labour, and Conservative - wanted to stop weaponised mass migration, they could do so. And, those that do arrive could be deported. As numerous other countries do with illegal migrants. That they don't, is further evidence that they are, indeed, intentionally complicit.
For example: A week or so into the protests and riots in the UK, the government threatened the public that it had teams of officers monitoring social media, and that it would hunt down 'keyboard warriors' it deemed to be complicit in fomenting unrest. PM Starmer, who warned that the UK needed a 'bigger reset', also said that they would be rolling out mass AI surveillance, and teams specifically tasked with tracking down protest and riot attendees.
Much of the British public were particularly infuriated to hear that police resources were being assigned to such tasks because, in just the last few years, there has been a surge in all kinds of crimes, and police are known to be attending as little as 40% of incidents. This suspect prioritization has become popularly known as Two-tier (Kier) policing.
So, when the British government wants to crack down, they do. However it would appear that British citizens are the primary target, and specifically those who would call out the government's incompetent and corrupt policies.
A more recent development seems to show that the intention is to add even more fuel to the fire, with the government announcing that it will 'scatter' illegal migrants throughout the country:
