Clinton lambastes Trump on tax leaks US vice-presidential candidates debate tonight; Nobel prize for physics awarded for work on exotic states of matter; Hurricane Matthew kills one in Haiti Hillary Clinton speaks at Ohio rally. Photograph: Andrew Harnik/AP Edward Helmore in New York Clinton: Trump 'represents the rigged system' Donald Trump supporters were treated to lengthy expositions on the 1990s real estate market and tax planning strategies on Monday as the Republican candidate sought to quell mounting unease over his financial past. "The unfairness in the tax laws is unbelievable," he told an evening rally in Loveland, Colorado, following suggestions he could have escaped paying taxes for nearly two decades thanks to declaring $916m in losses. Earlier his Democratic opponent Hillary Clinton said he was "taking from America with both hands and leaving the rest of us with the bill" and represented "the same rigged system that he claims he's going to change". Clinton continued: "How anyone can lose a dollar, let alone a billion dollars, in the casino industry is beyond me." His charitable foundation was on Monday ordered to suspend its fundraising in New York immediately for violating state law, the New York attorney general's office said. Donald Trump skirts the taxing questions and declares: I'm working for you now Kaine and Pence square off for debate Tim Kaine and Mike Pence prepare to face off on Tuesday night in what could be one of the least consequential vice-presidential debates ever staged. One describes himself as "boring". The other admits he is a "B-list celebrity". Rarely have two running mates been so overshadowed by the historically unpopular candidates at the top of the ticket. After Trump's deflating performance in the last presidential debate, "the onus on Pence to right the ship", says Aaron Kall, director of debate at the University of Michigan. Don't know much about them? Here is a veeps primer. Tim Kaine v Mike Pence: what to expect at the VP debate US suspends Syria talks with Russia The US has cut off contacts with Russia on a Syrian truce, dashing hopes of restoring a ceasefire, as a Russian-Syrian aerial bombing campaign intensified its focus on destroying hospitals in rebel-held areas. Washington also pulled out military personnel who had been dispatched to work with their Russian counterparts to mount joint bombing operations against extremist groups Islamic State and Jabhat Fateh al-Sham. Earlier, Vladimir Putin suspended a six-year agreement with Washington on the reduction of military stocks of plutonium as tensions between the two countries mount. Meanwhile Kurdish Peshmerga forces preparing to join the attack on Mosul, Isis stronghold in northern Iraq have made an urgent request for equipment to protect themselves from an Isis chemical attack. US suspends Syria talks with Russia over bombing of rebel-held areas British trio win Nobel physics prize for work on topology The Nobel prize for physics is to be shared by David Thouless, Duncan Haldane and Michael Kosterlitz for work on exotic states of matter that may pave the way for quantum computers and other revolutionary technologies. The scientists used a branch of mathematics called topology to redefine what was thought possible in materials. In work that began in the 1970s, they demonstrated that superconductivity – the ability of electrons to whizz through matter with zero resistance – was possible in thin surface layers of materials.

British trio win Nobel prize in physics for work on exotic states of matter Supreme court to examine racial bias in death sentence case In 1997, Duane Buck attended the sentencing hearing for killing his former girlfriend, Debra Gardner, and her friend Kenneth Butler. Walter Quijano, a then psychologist who was frequently called to testify in Texas capital trials, was asked by Texas prosecutors if "the race factor, black, increases the future dangerousness for various complicated reasons". Quijano responded that it did. On Wednesday, supreme court justices will be petitioned to reverse what civil rights lawyers claim was a flagrant case of racial discrimination, demanding a new colorblind sentencing hearing. Supreme court to address Duane Buck's 'racially tainted' death sentence Hurricane Matthew on track for US Hurricane Matthew, the category 4 storm currently lashing western Haiti with 145mph winds, is likely to at least brush the east coast of the US by the weekend, weather forecasters say. In Haiti, the storm is likely to drop as much as three feet of rain across hills where trees have been cut down, increasing the likelihood of flash floods and mudslides, threatening villages as well as shanty towns in the capital, Port-au-Prince. One person has already been killed. Matthew is forecast to sweep over Cuba to the Bahamas on Tuesday and possibly reach Florida – where a state of emergency has been declared – by Thursday as a major hurricane, though weaker than at present. Hurricane Matthew: one dead as violent storm hits Haiti Girl on a Train left on platform This hottest of literary properties lands with a lukewarm splat on the movie screen, writes film critic Peter Bradshaw. "The complicated web of narrator-switches, flashbacks and POV-shifts seems clotted and Emily Blunt – usually so witty and stylish – is landed with a whingy, relentlessly weepy role in which her nose hardly ever resumes its natural colour." He adds: "Lieutenant Columbo could have sorted it in five minutes." The Girl on the Train review: red herrings on the tracks signal problems Pound crashes after Brexit news The British pound has slumped below its lowest point against the US dollar for 31 years, to $1.275, following UK prime minister Theresa May's announcement that she would begin the process of leaving the EU in the first quarter of 2017. Pound hits 31-year low against US dollar, but shares soar – business live In case you missed it … There aren't many aspects of life that don't have an online alternative – and these days that includes death as increasingly popular webcast funerals prove. UK funeral director Max Webber estimates that between a quarter and a third of all their services make use if it. "We have a camera at the back of our chapel, which we turn on," he says. "We obviously let the minister know. Some of the ministers get the family to turn and wave to the camera."
