Newspaper headlines: 'Brexit plan to evacuate the Queen'
The Sunday Times devotes its front page to suggestions that the Queen and the Duke of Edinburgh could be evacuated from London and taken to a secret location in the event of riots triggered by a no-deal Brexit.
A Cabinet Office source said plans to rescue the royals were originally drawn up during the Cold War but have now been "repurposed" by Whitehall, in case there is civil disorder if Britain leaves the EU without a deal.
A government source, quoted by the Mail on Sunday, acknowledges such a scenario might seem far-fetched, but says contingency planners have to envisage "every possible eventuality".
The plans are ridiculed in the Mail by the leading Brexiteer, Jacob Rees-Mogg, who says they are the work of "over-excited officials".
There is widespread coverage of reports that Nissan could cancel its plans to produce the new X-Trail model at its Sunderland plant.

According to the Sun on Sunday, bosses at Nissan called the Business Secretary Greg Clark on Friday to inform him of the expected decision, although the company says jobs are unlikely to be affected.
The Financial Times says Brexit has caused uncertainty for the Sunderland plant, but the decline in diesel sales across Europe is "a more significant factor" behind the decision.

The Sunday Telegraph notes that today marks the deadline set by several European countries, including the UK, for President Maduro of Venezuela to call presidential elections.

For many gardeners, they're something of a pest - with a reputation for raiding bird feeders, stripping bark off trees and endangering their red cousins. But according to the Telegraph, the grey squirrel is now finding a warmer welcome. The director of a wild meat company tells the paper that squirrel is now his third biggest seller after venison and pheasant.
A restaurant owner at London's Borough market describes how he uses culled grey squirrels to produce a sustainable white meat, which he turns into tasty ragus.
