Newspaper headlines: 'We'll hold Iran to account' and O'Neill 'steps into history'

"Hollowed-out forces not ready for war with Russia" is The Sunday Telegraph's main headline, which joins The Sunday Express and Sunday People in leading on the report by the Commons defence committee.

The Telegraph says Nato countries have been warned they have just three years to prepare for a possible Russian offensive, and that in a peer-on-peer conflict, the UK will have exhausted its capabilities after two months. The Express says its polling suggests eight out of 10 people fear World War Three could break out this decade, and nearly half want a return to some form of national service.

The Sunday Times has interviewed Foreign Secretary Lord Cameron, who says Britain has the assets to keep it safe but admits the war in Ukraine keeps him up at night. He says the situation is like the 1930s, where the UK did not do enough to stop aggression. Lord Cameron says Britain needs to demonstrate it can keep providing Ukraine with weapons, as well as replenish its own stocks.

"Stepping into history" is how The Observer captions its picture of Northern Ireland's new first minister, Michelle O'Neill of Sinn Fein, who also features on the front of The Sunday Times and The Independent on Sunday.

The Observer has been investigating a drug rehab centre in Sussex. It says the Narconon clinic has been using near identical tactics to the Church of Scientology, which it says is the principal funder behind the trust that supports it. The paper reports that patients and staff members are made to do repetitive drills - following commands such as stand up and sit down for up to five hours a day for several weeks - in what's described as obedience training. Narconon, which is listed in an NHS directory, said it was not following a religious doctrine, and the drills had helped save lives. The Department for Health and Social Care declined to comment.

The Sunday Mirror reports that a Conservative trade minister told the tech firm owned by the family of Rishi Sunak's wife, Akshata Murty, that he would help it grow in the UK. Lord Johnson was said to have made the remarks to representatives of Infosys during a trip to India last April. The Department for Trade says its ministers regularly meet businesses to champion the UK as an investment destination, but the paper's editorial argues Rishi Sunak should publicly clear the air over what it describes as a perceived conflict of interest.

The Conservative former home secretary Suella Braverman has written in The Telegraph criticising churches over what the paper describes as their alleged support for bogus asylum claims. The suspect in the chemical attack in Clapham, who is from Afghanistan, was twice denied asylum before he converted to Christianity and was allowed to stay in the UK.

Ms Braverman writes: "Attend Mass for a few months, befriend the vicar, get a baptism date and bingo, you'll be signed off as a God-fearing Christian who will face persecution if removed to your Islamic country of origin". The Church said it was the role of the Home Office, not the Church, to vet asylum seekers.

The Sunday People reports the suspect's local diocese has no record of him switching religions. It says church leaders in Hexham and Newcastle have found no trace of the referee he's reported to have used to prove his conversion.

And The Sun on Sunday's lead story is that Kate Garraway will return to present Good Morning Britain next Thursday, less than a week after the funeral of her husband, Derek Draper.
