Newspaper headlines: 'Brexit chaos' warning and cabinet rows - BBC News
The Observer features a warning from former civil servants to Theresa May over Brexit, while the Sunday Times says the cabinet is "at war".
If the Observer is right, the mood in Brussels - a day before the next round of Brexit talks - is "cautiously optimistic."

But the message doesn't seem to have reached the cartoonists.

In keeping with the start of the holiday season, the Sunday Express offers an image of Theresa May at the wheel of the Brexit car - the back seat is crammed with people, all shouting advice: "Speed up!" "Slow down!" "Turn back!"

The drawing in the Sunday Times shows Mrs May and her cabinet colleagues entangled in a never-ending bill.

"What do you mean?" she complains. "This is just for starters!"

Of course both cartoons are about the seemingly inescapable politics of the subject.

According to the Observer, the kind of exit from the EU that Mrs May is pursuing has revealed "a picture of incapacity, incompetence, self-deception, dishonesty, partisanship, and harmful confusion".

The paper sees "the Tory hard Brexiteers" as "the lords of misrule."

The Sunday Telegraph asks what the term "hard Brexit" means and answers "really just Brexit with some negative branding".

If supporters of withdrawal want to cheer themselves up, the Sun on Sunday says they should just consider Tony Blair's latest intervention.

"As ever," the paper says, he ignored the will of the British people, providing "a classic example of the kind of arch-deviousness that became his stock-in-trade as prime minister".

The Sunday Mirror reports that a quarter of teachers who have qualified since 2011 have already left the profession, according to figures obtained by Labour.

It suggests their motives for quitting were low pay and harsh conditions.

Laura Jackson writes in the Sunday Express that she left after two years because the job was eroding her mental health.

She describes the miseries she experienced: the horrifying behaviour of the pupils towards each other and her, the open hostility of parents, the power cuts in her classroom and the crushing workload.

The Sunday Times thinks TV viewers may be shocked when the BBC reveals how much its better paid presenters earn.

The former newsreader Peter Sissons tells the newspaper things might get ugly when "some of the biggest egos" find out what their colleagues are getting.

The Sunday Telegraph says the corporation is also "braced" for embarrassment and rows on the grounds that "women are not being paid as much as men in the same jobs".

But the paper also notes that the salaries of "many stars" won't be revealed because they are paid through production companies or through the BBC's commercial arm.

The Observer expects more viewers to be excited by the return of Game of Thrones.

It says the drama "casts a shadow over the television landscape at least as large as that of one of its fire-breathing dragons".

But even more coverage is given to ITV2's Love Island, a show described by the Sunday Express as "racy."

The Sunday People says there's been a "sudden rise" in its popularity.

The Sun on Sunday asks its readers whether they have "never seen the hottest show on TV?" and offers an introduction to the contestants, the rules and the "lingo" they use.

Rosie Millard, in the Sunday Times, says her three eldest children "think and talk about nothing else" and she calls it "a mother's idea of hell".
