Newspaper headlines: Kate and Meghan display 'peace and goodwill'
Many of Boxing Day's front pages feature pictures of the Royal Family attending the Christmas Day church service at Sandringham.
Much of the attention is focused on the Duchesses of Cambridge and Sussex amid reports they had fallen out.
The Daily Mirror says the pair presented a "united front", while the Daily Express says it was "Christmas peace" for Kate and Meghan and the Daily Telegraph says they "put paid to rumours of a rift".
However, the Sun takes a more sceptical approach, saying the two women called "a Christmas truce". It quotes one royal source telling the paper that their appearance was "a bit uncomfortable".
Food and drink
Readers who enjoyed overindulging on Christmas Day might find the Daily Telegraph's lead story hard to stomach. It says proposals from Public Health England aim to limit the number of calories in convenience meals to 544 and in restaurant main courses to 951.
The paper says the plans - part of the government's childhood obesity strategy - have infuriated manufacturers, who have described them as too complex and confusing to be workable.
Meanwhile, a report in the Daily Mirror says women who drink should only do so with meals, to avoid the risk of liver damage.
It highlights research suggesting that female liver disease has increased by more than a third in the past 16 years.
The i says retailers will be offering bigger discounts than normal in the traditional Boxing Day sales.
It quotes analysts saying that with widespread deductions already offered, shops will be forced to cut prices further to get rid of unwanted products. The paper adds that many retailers have far too much stock and not enough cash.
Meanwhile, the Times's lead story is concerned with what bargain-hunters will use to carry home their booty. Under the headline "scourge of plastic bags for life", it says more than a billion of the bags are being handed out annually by supermarkets, undermining their claims to be reducing plastic waste.
It points out that retailers replace "bags for life" free of charge but that many customers only use them once.
Environmental campaigners are now calling on retailers to increase the cost of the bags to at least one-pound, to encourage people to use fewer of them, the paper adds.
'Alexa, you've burned my turkey'
Finally, the Sun is one of a number of papers to report on bad news for those who were given the Amazon Alexa device for Christmas.
It says the system crashed on Christmas morning as thousands of the voice-controlled virtual assistants were plugged in for the first time.
It's thought an overload of requests left the devices unable to function.
The Mail says the fault caused problems in many households; one user who was relying on the device to turn off his oven complained of a burnt turkey, while another stated he would have to talk to his family instead.
