A shakeup of staff inside Donald Trump's team is throwing increasing doubt over the role of campaign manager Corey Lewandowski, according to US media. Lewandowski is credited with being the brains behind the unlikely success of Trump's presidential campaign so far. But he has faced criticism in recent days over the team's understanding of delegate rules.

Trump has been loyal to Lewandowski, standing by him even as he came under fire for manhandling a reporter. However, the New York billionaire is said to have asked recent hires Paul Manafort and Rick Wiley to take the reins in upcoming states at the weekend.

With both Hillary Clinton and Donald Trump holding commanding leads in opinion polls leading up to today’s New York primary, there likely will be little drama when the winners are announced tonight.

There are, however, some key questions to keep in mind as the primary results roll in.

Can Donald Trump win 50% of the vote?

For the Manhattan real estate mogul it’s all about winning a majority of the vote. If he does that statewide, he’ll get 14 at-large delegates. Beyond that, it’s a battle in each of the state’s 27 congressional districts. When he hits 50% in one of those mini-battlegrounds, and he gets three delegates. Less than that and the bounty will be allotted proportionately.

Every delegate counts, as the front-runner’s path to securing 1,237 delegates – and the Republican Party nomination – is quite narrow. The difference between a good night and a great one for Mr Trump could be a few percentages here and there. If it looks like he’s comfortably above 50% statewide, he’ll be in good shape.

Can Hillary Clinton dominate? 

For the former secretary of state, the delegate count – while important - takes a back seat to the overall perception of the results.

Bernie Sanders has dismissed Mrs Clinton’s current lead as a result big wins in conservative-leaning southern states. A comfortable Clinton victory in liberal New York would effectively refute that line of attack.

A double-digit win would allow her to argue that the nomination is in hand and that the window for a Sanders nomination is effectively closed. Sanders’s five-state win streak would be a thing of the past, and the headway he made with those small-state victories would be effectively erased by the New York result.

Who’s in second? 

While Mr Trump is almost certain to coast to a victory in his home state, second-place in the New York Republican primary looks to be a toss-up. Ted Cruz has positioned himself as the de facto alternative to the front-runner, but John Kasich is still grinding along.

Mr Cruz has been given a frosty reception in the Empire State, thanks in part to the derision he heaped on “New York values” earlier in the campaign. So if the Ohio governor is going to pick up any ground, now is perhaps his last, best chance.

If Mr Kasich finishes ahead of the Texas senator in New York, and perhaps garners a handful of delegates by winning some congressional districts, it could give his campaign a bit of life going into a series of primaries in mid-Atlantic states next week that could also be more in tune with Mr Kasich’s brand of practical conservative politics.

Mr Kasich is mathematically eliminated from winning the nomination outright, but he’d have a stronger hand in an open convention if he’s riding a wave of electoral success.

After widespread concern over problems with the voting process, New York's chief auditing officer, Scott Stringer, has ordered a review , externalof the city's Board of Elections (BOE). It comes after the agency confirmed that more than 125,000 voters in Brooklyn had been removed from voter rolls. Voters also reported having trouble accessing polling sites.

The BBC's Suzanne Kianpour speaks to some Sanders supporters outside of his headquarters in Brooklyn, New York.

In a radio interview on hip-hop programme "The Breakfast Club" Hillary Clinton said she carries hot sauce in her purse. Some have criticised her for pandering to the African-American community - including Donald Trump - but she said she has loved hot sauce and hot peppers for a long time. 

Donald Trump cast his ballot at Manhattan's Central Synagogue earlier, surrounded by security agents. Meanwhile Hillary Clinton voted with her husband, former President Bill Clinton, at a school near their home in Chappaqua, in the north of New York state.

Trump and Clinton are the last presidential candidates to vote in the contest. Bernie Sanders voted in his home state of Vermont in March, while Republican challengers Ted Cruz and John Kasich went to the polls in Texas and Ohio.

We're back with the latest updates on the race to become the Republican and Democratic nominations for the US presidential elections in November. It's the turn of people in New York to vote in primaries seen as key for the current front-runners for both parties. Donald Trump is expected to beat his closest rival, Ted Cruz, but observers will be watching closely to see whether he can win a majority. On the Democratic side, Hillary Clinton - a former senator for New York - is hoping to beat Brooklyn-born Bernie Sanders.

Donald Trump's campaign released a new online advert on Wednesday, questioning whether Hillary Clinton could stand up to world leaders such as Russian President Vladimir Putin. The video posted to Instragram mocks the Democratic presidential candidate, using old footage of Mrs Clinton barking like dog. He said she would become a "punchline" among world leaders.

Years of carefully laid plans to repackage the Republican Party’s traditional ideas for a fast-changing US came "crashing down" on Tuesday when Senator Marco Rubio suspended his campaign for the presidency after a crippling defeat in his home-state primary, The Washington Post, external says.

The paper says that ever since Mitt Romney’s devastating loss in the 2012 presidential election, leading Republicans have charted a path back to the White House based on "inclusive rhetoric and a focus on middle-class issues".

"Nobody embodied that vision better than Rubio, a charismatic standard-bearer for conservative orthodoxy who readily embraced the proposals of the right’s elite thinkers," The Post says. "The senator from Florida spoke urgently and eloquently about raising stagnant wages and eradicating poverty and had an immigrant’s tale to match the rhetoric." On foreign affairs, he was a passionate defender of the party’s "hawkish tilt".

"But Rubio’s once-promising candidacy, as well as the conservative reform movement’s playbook, was spectacularly undone by Donald Trump and his defiant politics of economic and ethnic grievance."

The Hill reports, external that Trump's speech will be to a major pro-Israel lobby group, the American Israel Public Affairs Committee.

Barack Obama has warned that the 2016 White House race is damaging America's image abroad, the AFP news agency reports.

Lashing out at "vulgar and divisive rhetoric" in the race to replace him, Mr Obama, with Ireland's Prime Minister Enda Kenny at his side, said: "This is also about the American brand."

Meanwhile, US officials say there is an "intense focus" from their foreign officials on the 2016 presidential campaign and a "laser-like focus on the Trump campaign", AFP reports.

"It's a new element that we find ourselves meeting virtually every time we meet with foreign counterparts," said one administration official on condition of anonymity.

"They want to know what exactly is going on. Are these people serious? What does this mean for our bilateral relations. It ranges from puzzlement, to bemusement, to genuine concern."
