If you live in a marginal constituency, don't be surprised if a prominent politician turns up in your neighbourhood later. Party leaders will be breathlessly criss-crossing the country in a last-ditch effort to win votes. Boris Johnson will say the Tories are the only party who can "get Brexit done", while Jeremy Corbyn will say Labour offers a "vote for hope". Lib Dem leader Jo Swinson will say voting for her party can stop Mr Johnson getting a Conservative majority, and so prevent the UK from leaving the EU. 

The SNP, whose leader Nicola Sturgeon published an open letter calling Mr Johnson the "greatest danger to Scotland of any Tory prime minister in modern times", will argue it is the only party strong enough to "deprive him of the majority he craves". Brexit Party leader Nigel Farage will tell Leave voters in traditional Labour strongholds "not to waste your vote" on Tories who have little chance of winning. In Wales, Plaid Cymru's Adam Price will publish a draft law which would make lying by politicians a criminal offence.

A YouGov poll suggests the Conservatives are on course for a small majority of around 28, with a hung parliament or a larger Tory majority in the margin of error. The BBC's opinion poll tracker suggests the Conservatives retain a solid lead.

A series of gun battles in Jersey City, in the American state of New Jersey, has left six people dead, one of them a police officer. Gunfire was first exchanged at a cemetery just after midday on Tuesday, police say. It is believed two gunmen killed Joseph Seals - an officer who worked to confiscate illegal weaponry - as he approached them. After fleeing in a truck, they took shelter in a kosher supermarket and went on to fire "hundreds of rounds of ammunition" from high-powered rifles at armed law enforcement officials, including Swat teams and federal agents, police say. Five people died in the shop, including the suspected gunmen, with one survivor being treated for injuries, authorities say.

Fancy a chocolate muffin for elevenses? How about a 50-minute run to work it off? Setting out the "energy cost of food" by labelling the time it would take to walk or run off the calories could prompt people to indulge less and eat more healthily, scientists believe. Researchers from Loughborough University, who looked at 14 studies, say it could cut about 200 calories from a person's daily average intake. The Royal Society for Public Health agrees this could have an impact on society's problems with obesity. So, pizza tonight? Try a four-hour walk for afters.

The Guardian says parties are involved in a "final scramble for votes" in what both Labour and the Conservatives have called the "most important election in a generation". The Daily Mail, which backs the Tories, has a front-page comment telling readers "you MUST use your vote". Like other papers, it reports a poll suggesting the Conservatives are on course for only a narrow majority, with a hung parliament within the margin of error. "Game on?" asks the i, which says Labour leader Jeremy Corbyn is closing the gap. Read the full review.
