Donald Trump has a big poll lead in New York ahead of the April 19 primaries in the Empire State. But the mogul revealed on Monday that he has already lost the votes of two key supporters: his children Ivanka and Eric. The pair were not registered as Republicans and failed to meet the registration deadline. “They had a long time to register, and they were, you know, unaware of the rules, and they didn’t register in time,” Trump told Fox News. “So they feel very, very guilty.” Watch the interview in which he also poured cold water on suggestions that he would pick Ivanka as his VP.

Trump lashed out at the GOP electoral process after Ted Cruz won most of the delegates in Colorado over the weekend. The Texas senator notched up 34 delegates in the state where voters are excluded from a process in which party members pick the representatives that will head to the Republican convention in Cleveland. “That is not the way that democracy is supposed to work,” Trump railed. “The system is rigged. It is crooked.” Read more

We know that Pope Francis was unimpressed with Donald Trump after the pontiff accused the mogul of not being Christian because of his stance on immigration and wanting to build a wall on the US-Mexico border. But is the Pontiff leaning towards Bernie Sanders? The Vermont senator announced with pride on Friday that the Vatican has invited him to speak at a conference about social and economic issues – one of his signature subjects. But it turned out the invitation did not come from Pope Francis himself, so we might have to hold our breath a little longer. The Vatican story was a nice break for Sanders who has spent much of this week trying to explain why he was unable to explain one of his main goals – to break up the banks. Here is our story on what Sanders wants to do.

The Democrats and Republicans are focusing on New York, which holds its primary on April 19. Trump is back in force on Twitter after recovering from his disappointing loss to Ted Cruz in Wisconsin. He reminded people on Friday that running for president is not the only thing he does every day. “So great to be in New York. Catching up on many things (remember, I am still running a major business while I campaign) and loving it!” Read more

The 2016 political circus is travelling to the Big Apple, and some candidates are surviving the move better than others. On Thursday, Ted Cruz got a Bronx cheer from the New York Daily News. “Honey, how do we get out of the Bronx…Take the F-U Train, Ted!” read the paper’s front page, emblazoned with a photograph of Cruz and his wife Heidi. Read more

Donald Trump had a terrible night on Tuesday, although you would not know that from his Twitter feed, which went uncharacteristically dark for hours after it emerged that Ted Cruz had crushed him in Wisconsin, aka the Badger State. Looking beyond the headline results should make the tycoon even more concerned, as his Texas rival has started making inroads into some groups – lower-educated and lower-income voters – that had been fertile terrain for Mr Trump.

The creator of this Trump colouring book may need to add some kryptonite to the superhero image of the billionaire on the cover. As for Mr Cruz’s image, he likes to make a virtue out of the fact that he is anti-establishment (which has inspired T-shirts like this), but the Texan may need to change his tune now that the establishment is coming on board to defeat Trump. Read more

Donald Trump is clearly not satisfied with simply being the frontrunner for the Republican presidential nomination. Watch the video he tweeted out today, which suggests that he sees himself as Luke Skywalker. His Republican opponents, who are scared stiff that he will destroy the party, might prefer to say Anakin Skywalker.Trump is facing the prospect of losing to Ted Cruz in the Wisconsin primary on Tuesday. That would increase the odds of a contested convention in July, which in turn would raise GOP hopes that the establishment could parachute in someone to save the party. Increasingly, the whispers in Washington are about Paul Ryan, the Speaker of the House of Representatives, who has denied wanting the job, but has chastised Trump on several occasions recently. Read more

Within eight days, the International Criminal Tribunal for the Former Yugoslavia has delivered verdicts in two of its most important cases since its foundation 23 years ago.

Ted Cruz is famous for having almost zero friends in Washington. But the Texas senator seems happy with that situation and is not about to add Donald Trump to his circle even after the New York property mogul visited the US capital to attempt to build bridges with the Republican Party. Appearing on Jimmy Kimmel Live! on Wednesday night, Cruz was asked whether he preferred President Barack Obama or Trump more. Here was his response:

“I dislike Obama’s policies more, but Donald is a unique individual,” Cruz told the comedian. “If I were in my car and getting ready to reverse and saw Donald in the backup camera, I’m not confident which pedal I would push.” Read more

The Easter Bunny has been unkind to Donald Trump. On Tuesday his campaign manager, Corey Lewandowski, was charged with “battery” after a reporter alleged that the former state trooper had yanked, and bruised, her arm at a campaign event. Trump defiantly dismissed the claims and urged people to watch the video of the incident, which police in Florida police released after charging Lewandowski.

In a campaign that has made House of Cards seem tame, it transpired that one of the lawyers representing Lewandowski resigned as a top prosecutor in Florida in 1996 after being accused of biting a stripper. Speaking to reporters on his plane, Trump said he had urged Lewandowski to fight the charges. Texas senator Ted Cruz and Ohio governor John Kasich, the other Republican contenders, slammed Trump over the case. Read more

Your wife is lovely, and Heidi is the love of my life.” Speaking on television later, Cruz continued: “It’s not acceptable for a big loud New York bully to attack my wife … It is an action of a small and petty man who is intimated by strong women”. Read more
