Newspaper headlines: Rio Olympics begin and judge told 'explain yourself'
The Olympic opening ceremony happened too late for the papers to cover but most nonetheless look forward to the start of the Rio Games.
The Telegraph is one of many papers to use a picture of the Maracanã stadium illuminated by fireworks during a dress rehearsal.
"Let the Carnival Commence!" reads the caption.
The Telegraph also highlights how an unprecedented number of those British medal hopefuls are siblings with a record six pairs at Rio.
A sports psychologist tells the paper it makes sense. The age-old debate is between nature and nurture, he says, and those sibling athletes benefit from both.
On its front page, the Guardian chooses a similarly upbeat headline: "Let the Rio Games Begin!" above a big picture of one of Team GB's medal hopefuls, the cyclist Laura Trott.
But amid the attempts to capture the excitement, there are also more reports of setbacks and shortcomings.
The Daily Mail's headline is "sinking feeling" as it describes how nine Team GB kit bags have gone missing, including some of those belonging to the swimming team, who begin competing today.
The Daily Mirror leads on a claim that Team GB stars are being guarded by members of the SAS.
It quotes an unnamed source as saying they would be the first response in the event of a major incident. The MoD tells the paper it doesn't comment on the special forces.
Meanwhile, the Times focuses once more on the issue of Russian doping.
Vitaly Stepanov - the whistleblower who helped expose the scandal - tells the paper the decision to allow 271 Russian athletes to compete at Rio will "promote cheating".
The Telegraph uses a Matt cartoon to make a similar point. In it, two drugs testers gaze at an unfeasibly large mosquito. One tells the other: "This is what happened when it bit a Russian athlete."
An 'unnecessary expense'
Following news of Justice Lowell Goddard's resignation as the chair of the child abuse inquiry, several papers use their editorial columns to consider what should happen next.
The Sun says she can't be allowed to "scuttle off home with no questions asked". The paper says such questions include, "What has she done?" It also asks: "Shouldn't Britain get a refund?"
For Charles Moore in the Telegraph, now Dame Lowell has quit "the great child abuse inquiry should stop too".
"Its rules are unfair, some contrary to proper legal procedures. Its remit is almost literally endless. Its unnecessary expense is huge. It is not, and cannot be, properly equipped to bring justice to thousands of individuals who feel wronged", he writes.
The Guardian disagrees, saying the focus should be on the abuse victims. In its editorial, it rejects calls for the approach to be changed..
The "process is too big and important to threaten the confidence of those who have invested in it by further delay", the paper argues, concluding: "It must get on with its work, now."
The Times leads on what it calls the "great dental rip off" of NHS dentists needlessly extracting patients' teeth.
The paper says it's because they're paid the same to remove teeth as to carry out complex treatment to save them. The system also encourages dentists to "cram in" as many procedures as possible, with some billing for 60 check-ups per day.
Last year it says, 10 dentists claimed for work equivalent to £450,000.
The Guardian, meanwhile, reports a more encouraging health-related story: a new drug which it says has been described as a potential "game-changer" in the treatment of asthma.
It says the development of Fevipiprant opens up the possibility that half a million British people with the condition could take a pill twice a day instead of relying on inhalers.
The charity Asthma UK says the research shows "massive promise", but tells the paper more research is needed, and an over-the-counter pill is some way off.
Booze ban for MPs?
The Times says it has learnt MPs are to be moved out of the Palace of Westminster for the first time since it was bombed during World War Two.
It says it has seen a report by a parliamentary committee suggesting MPs should go to the nearby Department of Health building, while a multi-billion pound refurbishment of the Palace is carried out.
The paper identifies two sources of anxiety for MPs.
The first is the "public backlash" at the cost of the project. The second, it says, is the fact that their new potential home - unlike their old one - is unlikely to have anywhere that sells alcohol.
Staying on the subject of booze, the Financial Times considers the paradox facing the Campaign for Real Ale, or Camra.
As micro-breweries mushroom, Camra should be enjoying what the FT calls a "golden age in real ale". Yet its "efforts to add youthful fizz are falling flat", it says.
The problem appears to be that Camra doesn't think what younger drinkers call craft beer conforms to its definition of good beer. That, and its image problem.
As one insider concedes, it doesn't help when, as he puts it, current members "look like old characters from the comic, Viz."
