"One rule for them!" proclaims the front of the Daily Mail. It describes the SNP MP Margaret Ferrier as "reckless" for travelling by train to London from Scotland despite experiencing Covid symptoms, then returning home after receiving the positive result.
The headline in the Mail's Scottish edition refers to the MP's "Covid trip of shame", while the Herald, which is based in Glasgow, says one person is self-isolating after being in close contact with her.
Under the headline, "plague dimwit", the Sun's leader accuses Ms Ferrier of hypocrisy. It refers to the fact that she called for the resignation of Prime Minister Boris Johnson's senior aide, Dominic Cummings, after he drove from London to his parents' farm in County Durham during the national lockdown. The paper describes Mr Cummings' action as "a thousand times more responsible" than Ms Ferrier's and demands a police investigation into what she has done.

If we don't, Britain will be just weeks from leaving the EU courts' remit anyway."
Writing in the Daily Telegraph, Martin Howe, a barrister from the pro-Brexit group Lawyers for Britain, argues that if the European Court of Justice were to rule against the UK in such a case, its punitive powers might be limited. "There is no actual means by which an ECJ judgment can be enforced against a sovereign state which defies it," he writes.
The Daily Mirror points out that, whatever the legal realities, the row "risks souring UK-EU trade talks after optimism of a deal".
The Times says allies of Home Secretary Priti Patel are accusing the Foreign Office of being "at war" with the minister over her plans to deal with asylum seekers. According to the paper. they allege that officials have leaked "bizarre and unworkable" policies in order to discredit her. These are said to include artificially creating waves to push back boats in the Channel and fouling their propellers with chains. The Times reports that Foreign Office sources have dismissed the claims.
The front of the Financial Times has the headline: "Floating walls in Channel considered in latest plan to block asylum seekers". The paper says it has seen a leaked document from trade body Maritime UK, which it suggests was asked by the Home Office to look at the possibility of erecting temporary underwater fencing "in one of the world's busiest shipping lanes". The FT says it's been told by Marine UK that it didn't think the plan was "legally possible".

The New York Times' website turns its attention to the decision by the Republican governor of Texas, Greg Abbott, to allow voters to drop off postal ballots at only one location per county.
