The cost of the deal to transfer the sovereignty of the Chagos Islands to Mauritius is the lead for the Telegraph and the Times – which both question the prime minister's claim that the total "net cost" of the deal to maintain a key military base there over a century would be roughly £3.2bn.
The Telegraph says its own analysis shows it is more likely to be around £30bn, a figure also suggested by the Conservatives.
It quotes the shadow foreign secretary, Dame Priti Patel, as saying that Labour are lying to British taxpayers with their "dodgy accounting".

The government's plans to release some prisoners in England and Wales early is the lead in the Daily Mail and the Daily Express.
The Express has spoken to the Justice for Victims campaign group – which includes the parents of Sarah Everard who was murdered by a policeman in 2021.
The paper says the group has described the plans as an "insult to all victims".
The i Paper carries a warning from former MI6 chief Sir Richard Dearlove that the Energy Secretary Ed Miliband's net zero plan is a threat to national security.

It says the trend may be contributing to the declining birthrate in Western countries – which has been happening in the UK since 2010.
