"How could they stoop so low?" asks the Daily Mail.
The paper accuses Downing Street of launching a new smear campaign and this time, the government scientist David Kelly is the target.
The paper says after a day of denials, Number 10 confirmed a senior official had branded Dr Kelly a "Walter Mitty" style fantasist.
That official is identified as Tom Kelly, one of Tony Blair's spokesmen, by several papers, including the Financial Times.
Number 10, says the Mirror, is up to its neck in a sickening campaign to blacken Dr Kelly's name.
Immigrant health screening
There is a mixed response to Conservative proposals to enforce health screening for all immigrants coming into Britain.

Leslie preoccupies tabloids
Not for the first time in recent weeks, the Daily Express devotes its first half a dozen or so pages to the row between the television presenters John Leslie and Ulrika Jonsson.
The Sun reports Ms Jonsson is flying to Sweden to escape the media scrutiny.
Her spokeswoman tells the paper she has no comment to make.
Mr Leslie's comments span seven pages of the Express.
The Times warns the cost of a loaf of bread is about to soar in line with the heat.
It says large quantities of French wheat have been frazzled by the sun.
The knock-on effect could be 8p on the price of a loaf.
Meanwhile the Independent says the scorching weather has meant some English apple harvests are two weeks early.
