Newspaper review: Cameron's Scotland stance debated
David Cameron's intervention in the SNP's plans for a referendum on Scottish independence provides a topic of debate in the papers.
Most urge him, in the words of the Daily Mirror, to "tread carefully".
The Daily Mail has deep reservations about Mr Cameron's conditions on the timing and terms for a binding vote.
Might not this raise hackles among chippier Scots over high-handed English interference so playing into the hands of Alex Salmond, it asks?
For the Financial Times, honest arguments will save the UK, not judo moves and political ploys.
If Mr Cameron wishes to preserve the union, the Independent suggests, he must focus not just on Mr Salmond but also on putting a stronger case in favour to the Scottish electorate.
The Daily Telegraph says it is true Mr Cameron is interfering but he is legally entitled to.Tax draw
Ed Miliband's speech on Tuesday - warning his party to accept it will have to address the deficit at the next election - is the Guardian's lead.
The paper says he will be setting out a new direction for his party.
The main story in the Times says David Cameron, Gordon Brown and Ed Miliband are expected to be summoned to give evidence to the Leveson Inquiry.
The Times also reports that people who complete their tax returns early could be entered into a draw with a top prize of £100,000.
A government source tells the paper: "Evidence suggests that prize draws can be effective in motivating people".
The Independent reports on research that found "no association" between higher immigration and rising joblessness.
The National Institute of Economic and Social Research study contradicts the claims of activists, it notes.Camera change
The Sun says a study suggests that nicotine patches can delay the onset of Alzheimer's disease.
US researchers found that the chemical appears to stimulate the nervous system, firing up ailing brain cells.
Finally, the Guardian says smartphones are now officially replacing traditional cameras as the most popular device for taking pictures.
Sales of cameras fell 30% in value in 2011, with the launch of the iPhone 4 accelerating the decline.
