Newspaper headlines: Steven Woolfe, Labour reshuffle, Stonehenge dog and children's watch

Pictures of stricken UKIP MEP Steven Woolfe on the floor at the European Parliament after an altercation dominate the papers.

The confrontation, understood to be between Mr Woolfe and colleague Mike Hookem, took place during a heated meeting of UKIP members of the parliament.

Mr Woolfe later collapsed and is said to be recovering in hospital, and the party has launched an investigation.

The Guardian says: "Steven Woolfe, the favourite to become leader of the UK Independence Party, has been hospitalised after a dramatic altercation with a fellow UKIP MEP in the European Parliament.

"Woolfe, who later said he was recovering well and 'smiling as ever', collapsed during a vote in the Strasbourg parliament and was taken to hospital in what was described as a serious condition."

The Times reports: "The fracas between Steven Woolfe and Mike Hookem yesterday erupted at a UKIP meeting that had been called to 'clear the air'.

"Mr Woolfe, a candidate for the party's leadership, faced anger from his colleagues after allegations that he had been in talks with the Conservative Party over the possibility of defecting."

The Daily Telegraph says a photograph obtained by ITV News showed Mr Woolfe spread-eagled and face down, while an attendant leaned over him.

The i says: "Even by the fractious standards of UKIP, the hospitalisation of its potential leader after going toe-to-toe with a colleague represents an extraordinary escalation in its internecine strife."

The Mail pictures Mr Woolfe in his hospital bed smiling and giving the thumbs-up, and describes the fracas as "astonishing".

The Express reports: "UKIP was rocked last night after the front-runner to take over as leader spent the night in hospital following an apparent altercation at a meeting of MEPs."

The Financial Times remarks: "It was the latest in a series of dramatic events to shake politics since the June vote to quit the EU, including David Cameron's replacement by Theresa May as prime minister, the Labour leadership election and the resignation of Nigel Farage as UKIP leader."

On to upheaval in another political party, and Jeremy Corbyn's shadow cabinet reshuffle after being re-elected as Labour leader is considered by the papers.

Changes included appointing Diane Abbott as shadow home secretary and Shami Chakrabarti as shadow attorney general.

As the Guardian sums up: "In a sign that Corbyn has tightened his grip over the party, Abbott, a friend whose constituency neighbours the leader's, has been promoted from shadow health secretary to shadow home secretary.

"Lady Chakrabarti, ennobled by Corbyn weeks after completing a controversial report on anti-Semitism within the party, has been confirmed as shadow attorney general.

"He also appointed Dawn Butler to be shadow minister for black and minority ethnic communities, which means there are five MPs in the shadow cabinet from black and ethnic minority communities - the highest ever number.

"But in a dramatic move that dismayed many MPs, Rosie Winterton, the opposition chief whip, was replaced by Gordon Brown's former government fixer Nick Brown."

The i notes that Lady Chakrabarti's peerage proved controversial because it followed her report into anti-Semitism in the Labour Party, which critics complained was a "whitewash".

According to the Times: "Jeremy Corbyn reasserted his authority over Labour last night as he sacked a senior moderate from his team and appointed close allies to key posts.

"In a shock move that some MPs branded the most hostile act of his leadership, Mr Corbyn dismissed Rosie Winterton as chief whip and replaced her with Nick Brown, one of Gordon Brown's former political enforcers.

"Her dismissal marked the start of a shadow cabinet reshuffle that saw Mr Corbyn hand the key post of shadow home secretary to Diane Abbott, his staunch ally.

"Baroness Chakrabarti, the former director of Liberty, the human rights group, was appointed shadow attorney general just two months after being made a Labour peer."

The Times reports on a 7,000-year-old find that has become a serious conundrum for archaeologists.

This is because the tooth of an Alsatian dog that lived in Yorkshire as a puppy was found hundreds of miles away at what was to become Stonehenge where it died.

The Times says the find may make it the first recorded journey of a domestic animal and therefore add to growing evidence that the Stonehenge area was a place where people gathered thousands of years before the stones were put up.

Durham University's Bryony Rogers, part of the team that analysed the tooth, told the Times: "This dog was not local. It could have come from as far away as York."

The Times comments: "This was a prescient Alsatian. Seven thousand years ago, two millennia before the great monument was erected in Wiltshire, one dog knew that the site of Stonehenge was worth a detour.

"Having dug up and analysed a canine tooth that lurked under Blick Mead, a mile away, an archaeologist from the University of Buckingham says that the dog, probably accompanying its human master, trekked 250 miles from Yorkshire for the visit."

Finally, looking ahead to Christmas, the Telegraph says London toy shop Hamley's believes that a gadget that helps children as young as four count their steps will be one of the top 10 gifts.

The Telegraph says the £43 smartwatch, which features a pedometer to help children track how much walking and running they are doing, has drawn concern that it puts too much pressure on young people to exercise.

In an editorial, the paper says: "Many parents are grateful to see offspring active instead of slumped in front of a computer. But isn't this constant measurement an obsessive kind of displacement activity?

"Instead of exercise being a by-product of rushing around enjoyably playing cops and robbers, the aim becomes the clocking up of footsteps.

"So when the One Great Scorer comes, he'll ask not how you played the game, but your electronic read-out."
