"The kangaroo tried to drown the man," she said. "I realised what was happening and told my husband [who couldn't see the fight from his seat] to get out the car and help."But then the kangaroo appears to have been spooked - perhaps by the approaching car driven by Mr James's friend - allowing him to escape down towards Ms Lees, who has since tried to warn as many neighbours as possible.

"The kangaroo was trying to drown me," he told Ms Lees, who was able to say she had seen it all."I just remember being under water and kicking and screaming and carrying on," Mr James later told ABC.It was, he said, "pretty traumatic for a while there".

Kangaroos have been known to appear to attempt to drown their foes - although these are usually animals the size of dogs."There's a very strong instinct - kangaroos will go to water if they're threatened by a predator," he told the news network.

However, he said, the behaviour is likely more about protecting themselves than drowning their foe.

That is unlikely to make Mr James feel any better about Friday morning's altercation - especially as he told Ms Lees that just 12 months ago he had fended off another attack, that time by a great white shark.Tony Blair, who opened the doors in 2004, recognised this in his autobiography A Journey. The "tendency for those on the left was to equate concern about immigration with underlying racism. This was a mistake. The truth is that immigration, unless properly controlled, can cause genuine tensions… and provide a sense in the areas into which migrants come in large numbers that the community has lost control of its own future… Across Europe, right wing parties would propose tough controls on immigration. Left-wing parties would cry: Racist. The people would say: You don't get it."

Sir Keir has felt some of that heat from his own side since launching the White Paper. In response to his warning about Britain becoming an "island of strangers", the left-wing Labour MP Nadia Whittome accused the prime minister of "mimic[king] the scaremongering of the far-right".The Economist, too, declared that Britain's decades of liberal immigration had been an economic success - but a political failure.

There is a world of difference between Keir Starmer and Enoch Powell. Powell believed Britain was "literally mad, piling up its own funeral pyre" and that the country was bound to descend into civil war. Sir Keir says he celebrates the diversity of modern Britain.But even if his plan to cut migration works, net migration will continue to flow at the rate of around 300,000 a year. Sir Keir's plan runs the risk of being neither fish nor fowl: too unambitious to win back Reform voters; but illiberal enough to alienate some on the left.
