The Daily Telegraph says No 10 is braced for another by-election as pressure mounts on Chris Pincher to stand down as an MP.
The Daily Mail says less of a swing would be needed for the Conservatives to lose the seat than the Liberal Democrats achieved in last month's by-election in Tiverton and Honiton.
The Guardian says the spotlight has turned on what the prime minister knew of the allegations against the MP, before he was appointed to his position in the whip's office.
According to the Telegraph, airlines using Heathrow Airport are re-working their summer schedules with a new wave of flight cancellations expected to be announced next week.

The Daily Express says Boris Johnson has backed a revolutionary plan to allow 50-year family mortgages that can be passed on to the next generation.
The paper says such an idea would make it more achievable for parents to help their children own a home.
"And to the children, I leave my mortgage debt," suggests the Daily Mirror.
The Telegraph says ministers think the plans would make it easier for buyers to get on the housing ladder in more expensive areas of the country, where the average home is now worth up to 11 times more than the average salary.
But the Financial Times is warning that the housing market is cooling as a result of the fastest rise in mortgage rates for a decade.
After the disappointment of Emma Raducanu and Andy Murray crashing out of Wimbledon in the second round, the Mail says there was "double delight for Britain" as Heather Watson and Cameron Norrie both reached the fourth round for the first time, under the headline: "They smashed it."
Above a photo of the British number four on its front page, the Telegraph says "winning proves elementary for Watson".
The Times says Watson has "banished her third-round demons" after 43 attempts, while Norrie's "relentless style is starting to win hearts and minds - not just matches".
The Guardian reports some less welcome news for the organisers of the tournament.
It says Wimbledon has been accused of using "bizarre" reasons to sack temporary staff, who are not needed because attendances have been lower than expected.
The paper says several people lost their jobs for going to the toilet without asking, while others were sacked for sitting on the hill with a drink - after their shift had ended.
In a statement, the All England Club tells the paper: "We meet annually with each of our major contractors to agree terms and conditions of employment, which are shared with all potential employees."
