Newspaper headlines: Corbyn's 'Brexit betrayal' and snow 'chaos'
Labour leader Jeremy Corbyn's expected commitment to a post-Brexit customs union is featured in several papers.
His speech later will "snub" Labour voters, the Mail says, as the move would allow free movement to continue yet block any future non-UK trade deals.
But the Telegraph says Mr Corbyn's speech comes amid a deep split within the Conservative Party over the issue - as five pro-European Tory MPs tabled a Commons amendment that could force the PM's hand into accepting a customs union arrangement.
The New Statesman suggests it should now be relatively easy for Labour to peel these rebels away from the government when it comes to some key votes.
In the Sun's view, Mrs May should stare down the Tory rebels and stick to her commitment to what it calls a "full-fat" Brexit. That's what the public voted for, it says.
However, the Mirror argues that Mr Corbyn's embrace of tariff-free trade, while also accepting migration controls, is his bid to acknowledge the referendum result without damaging the economy.
While options around trade after Brexit dominate discussions, the i says a UK-US deal could mean lower quality dairy products on offer in Britain.
The paper reports that US milk from cows with infections could be sold to British shoppers if the country's powerful dairy lobby gets its way. According to the i, the lobby has suggested it wants the UK to relax its regulations on milk quality as part of the price for a transatlantic accord.
The week's freezing temperatures and snow forecast for much of the UK make the front of the Express, the Mirror and the Star.
"Beware beast from the east" is the Mirror's headline. It says emergency shelters have been opened and charities are appealing for urgent donations of warm outdoor clothes for those in need.
The Express reports forecasters have warned of possible power cuts, travel chaos and loss of mobile phone signals. According to the paper, the army is at the ready with hundreds of soldiers on standby to deal with contingencies and emergencies.
Millennials have been branded "Generation Fat" by the Mirror. Several papers report the study suggesting nearly three quarters of them will be overweight or obese by the time they approach 40.
The Telegraph points out that they have probably had more healthy living and dietary advice than any previous generation - yet it has fallen largely on deaf ears.
Meanwhile, doctors warn that children are finding it increasingly difficult to hold pens and pencils properly because of time spent on touch screen devices.
One doctor told the Guardian it's easier to give a child an iPad than encourage them to do muscle-building play such as building blocks, cutting and sticking, or pulling toys and ropes.
Changing the recipe?
And finally, the Telegraph reports the price of hot cross buns is set to soar this Easter because of a global shortage of raisins, sultanas and currants.
The paper says the wholesale price of dried fruit has been pushed up by the wildfires at vineyards in California last autumn, and that means the buns will cost more than usual.
But you'll likely still get your hot cross bun as bakers are expected to swap the dried fruits for alternatives, including chocolate chips and orange peel, to keep costs down.
