Tuesday's papers are dominated by news of the formal identification of Nicola Bulley. Her family said officers had confirmed their worst fears when the mother-of-two was found on the banks of a Lancashire river on Sunday, more than three weeks after going missing, the Daily Mail reports. 'Nikki... we can let you rest now' is the Daily Mail's headline, reflecting their grief.

The Mirror also carries the tribute from Ms Bulley's family: "We will never forget Nikki, she was the centre of our world."

The Sun describes the tributes as "poignant" and features a smiling Ms Bulley on its front page.

The Express carries more from that tribute. The paper reports that her relatives admitted they would "never be able to comprehend what Nikki had gone through in her last moments and that would never leave us".

Ms Bulley's family also criticised parts of the UK media following the discovery of her body. In a statement read on behalf of the family by Det Ch Supt Pauline Stables, they claim that some members of the press "misquoted and vilified" their friends and family, the i newspaper reports. The statement also took aim at ITV and Sky News who the family said made contact with them "when we expressly asked for privacy", the paper says. The BBC understands Sky News had an "open dialogue" with Ms Bulley's family since she was reported missing. The BBC has approached ITV for a comment.

US President Joe Biden's surprise visit to the Ukrainian capital Kyiv also features prominently on many of Tuesday's front pages. The FT reports on Mr Biden's "unwavering support" for the embattled nation as he announced a further $500m in military aid.

The Daily Telegraph features an image of Ukrainian President Volodymyr Zelensky and Joe Biden embracing one another on its front page. But its main story is on comments made by former prime ministers Liz Truss and Boris Johnson who are both urging their successor, Rishi Sunak, to send fighter jets to Ukraine. In her first intervention in the House of Commons since resigning as prime minister, Ms Truss said she "could not wait to see fighter jets over Ukraine", the paper reports.

The Times also features stories on the Nicola Bulley case and Biden's visit to Ukraine. But its main story is on reports some ministers are prepared to resign from Rishi Sunak's government over his Brexit deal if it risks Northern Ireland's place within the UK. The paper says there is a mounting backlash among Eurosceptic Conservative MPs to the deal.

The Guardian turns its attention to the inquest of the victims of the Plymouth shootings. The inquest jury found "catastrophic" failings allowed the gunman, Jake Davison, to legally possess a shotgun that he used to kill five people in August 2021. Senior police officers, families of the victims and anti-gun campaigners are calling for a "radical reform" of the firearms licensing system, the paper says.

Junior doctors have voted overwhelmingly to join Britain's growing wave of strikes, the Metro reports. Out of 37,000 British Medical Association members who voted, 98% backed their first industrial action since 2016, the paper says. A 72-hour walkout is being planned in their fight for a 26% pay rise, the paper says.

And the Daily Star leads with the row over publishing changes made to children's author Roald Dahl's books. The prime minister has weighed in, with his spokesman saying works of fiction should be "preserved not airbrushed". 'Battle of the BFG' is how the Star frames the debate.
