Newspaper headlines: 'Business rates battle' and the £6bn bill
The Prime Minister Theresa May makes several of the front pages after her surprise appearance at the Brexit debate in the House of Lords on Monday.
The Daily Express says she "dramatically confronted peers over a plot to delay Brexit" and the Sun says she "stunned" the upper house by "staring down rebellious Lords in person".
Writing in the Daily Mail, Quentin Letts says Mrs May "scowled, she shook her head, she scratched her knee. She was watching them and her tail was swishing".
The House of Lords also makes The Daily Mirror front page, which says that peers are facing a new clocking-in scandal. It picks up an allegation in a BBC TV programme - that one lord signed in to claim his £300 allowance - then returned to his taxi which was waiting outside.
The paper itself reported similar claims four years ago and its scathing editorial accuses some lords of a "scandalous abuse of public funds", describing them as "vermin in ermine".
Several papers highlight conflict within the Conservative Party over changes to business rates in England and Wales.
The Times says the Communities Secretary, Sajid Javid, is being accused of "misleading" his own MPs with an analysis of the revaluation he sent to them at the weekend to try to head off a backbench rebellion.
The Mail views his attempts to reassure the rebels as a "Dodgy Business Rates Dossier" that underestimated the rate rises faced by small firms.
Most people have heard of a "granny annexe" for elderly relatives but the Times reports on a new phenomenon in home extensions.
The paper says so many university graduates are moving back in with their parents that there's been a surge in what architects have dubbed the "graddy annexe". It puts the trend down to high rents and the difficulties in saving for a deposit to get on the property ladder.
The Guardian leads with its analysis that crashing out of the EU with no trade deal would saddle British exporters with £6bn a year in extra costs.
As part of a series on the implications of Brexit, it says its work "reveals the limited options facing UK negotiators just weeks before Brexit talks start". The paper says the £6bn figure is what would happen if Theresa May fell back on World Trade Organisation rules and their resulting tariffs.
It suggests the implications of this Plan B "remain poorly understood within Whitehall".
And a woman who claims to be using Britain's oldest carrier bag is featured in several papers including the Daily Express. It has a photo of 65-year-old Sue O'Dowd, who's a grandmother from Shropshire, proudly holding the Tesco bag which celebrates the store's 50th anniversary - in 1981.
She has kept it for 36 years, through five house moves, and now uses it to store her knitting wool.
