Newspaper headlines: 'Barbs fly at Brexit talks' - BBC News
A war of words between UK and EU negotiators in Brussels makes many of Friday's front pages.
The end of the latest round of Brexit talks provides the lead for many papers.

The Guardian highlights the view of the EU's chief negotiator Michel Barnier that the UK's approach is nostalgic, unrealistic and undermined by a lack of trust.

"You can't bully us Mr Barnier," is its headline, saying his comments enraged the British side.

The Times emphasises an EU demand that the UK pays billions of pounds in foreign aid to Africa as part of its financial settlement with Brussels.

Business paper City AM sums up the problem as "money trouble", and says deadlock over the so-called divorce bill has triggered fresh alarm that trade talks could be shunted into next year.

The Financial Times and the Daily Mail have a photo of EU Commission President Jean-Claude Juncker greeting former PM Tony Blair with a kiss.

The Mail calls it a "nauseating love-in" that "reminds us why we were so right to get out".

The Guardian, which publishes an investigation into the gambling industry, claims online casinos are targeting people on low incomes and those who have stopped gambling.

In an editorial, the paper says the record fine levied on one company on Thursday is a sign that the UK has a gambling problem and that greater regulation is needed.

"Making the necessary changes will be painful," it acknowledges, "but the costs to public health cannot be ignored".

The Times says for an industry that relies on expert judgement in studying form and setting odds, betting operators have an uncanny knack of shooting themselves in the foot.

It says modest cuts in stakes and prizes might be enough to satisfy critics, but the industry's poor record on responsible gambling is shortening the odds of a drastic outcome.

The Daily Telegraph is among the papers to concentrate on the role of a sat-nav in the alleged terror attack outside Buckingham Palace a week ago.

Evidence taken from the car of Mohiussunath Chowdhury, who appeared in court on Thursday, suggests he programmed his sat-nav for Windsor Castle.

However, the in-car system is believed to have taken him to a central London pub of the same name rather than to the castle itself.

The Times and the Sun point out that the suspect was a driver for taxi firm Uber.

Trying to stop yourself yawning actually increases the urge, according to a study published in the i newspaper.

The Daily Express focuses on a different aspect of the research, which suggests that studying contagious yawning could hold the key to a future cure for dementia, as the tendency to catch a yawn is controlled by a particular part of the brain.

The Daily Mail says Italians have been left "fizzing with rage" at claims that too much Prosecco damages your teeth.

But the Daily Telegraph says they have misunderstood the British attitude to health - saying that even definitive proof that something is bad for you is no guarantee of a fall in sales.

The paper says Prosecco will remain popular as long as it remains a budget alternative to Champagne.

The Times considers whether criticising other countries' popular exports is a clever post-Brexit strategy.

"Those Leonardo and Michaelangelo guys are overrated, Roman Catholicism is a passing cult," the paper muses, before concluding that the idea may require further refinement.
