'Rioting thugs' and affordable homes 'stand empty'

A handful of the front pages focus on a warning from police about the possibility of unrest at the weekend.

According to the Times, the Justice Secretary Shabana Mahmood has told police chiefs there is enough space in prisons if the disorder escalates significantly. The paper says one contingency plan involves moving prisoners to jails in other parts of the country in order to ensure there are enough free cells.

The young person whose family originally told the Sun the former BBC presenter Huw Edwards had paid them for sexually explicit photos when they were a teenager, has given an interview to the Daily Mirror. The 21-year-old man, who is not named, tells the paper he now feels he was "groomed" by Edwards. He alleges the newsreader "fed on his vulnerability", knowing that he had recently become homeless and needed money. Edwards has not commented on the claims.

The Sun newspaper carries an account from the young man's step-father, who says he went to confront Edwards at a railway station in May last year, after discovering they had planned to meet there. Edwards wanted the young man to sign a non-disclosure agreement, the man claims. A police investigation into the allegations earlier this year found no evidence of criminality.

The Telegraph reports on an investigation carried out by the Ministry of Defence after it emerged that software used by Britain's nuclear submarine engineers was designed in Russia and Belarus. The paper says the inquiry found the firm that outsourced the work to developers in Siberia and Minsk initially kept it secret, but later discussed whether it could disguise where the workers were based by giving them false names of dead British people.

The shadow defence minister James Cartlidge is quoted as saying "the UK must not be over-reliant on certain suppliers for items that are significant for our critical infrastructure". The paper says the investigation concluded in February last year. A spokesman for the company says it regularly reviews its processes and enjoys transparent relationships with customers.

The first brain implant made of graphene is set for clinical trial in Manchester this month, according to the Financial Times. The paper says the trial involves placing electrodes made of a single layer of carbon atoms onto a patient's brain during surgery to remove a tumour at Salford Royal Hospital. If successful, researchers hope the graphene implant will lead to better treatment for conditions such as epilepsy and Parkinson’s Disease.

There is a plea by physiotherapists in the Guardian for people not to attempt the moves of their favourite Olympic athletes, after a spate of injuries. An NHS physio, Matthew Harrison, gives two recent examples: he says one patient damaged his wrist ligaments after being inspired by the skateboarding, and another suffered bruising after copying some of the lifts involved in women's rugby.

The paper also reveals that the Mission Impossible actor Tom Cruise is expected to perform a few stunts of his own for the Olympics closing ceremony - including abseiling down the Stade de France.
