Newspaper headlines: 'Hostile act in Parliament' and dog 'terror on streets'

Rishi Sunak raised concerns about interference from Beijing with China's premier while at the G20 in India

Many of Monday's papers focus on the arrest of a parliamentary researcher, amid allegations he was spying for China. The story has prompted some Conservative MPs to renew calls for China to be categorised as a threat.

The Daily Telegraph reports that British intelligence services are "poised to unmask" a number of Chinese spies operating in Westminster in the coming months. Quoting "Whitehall sources", the paper says suspected foreign spies working in the Commons face being detained under new espionage laws passed this summer.

The legislation introduced an offence of "foreign interference" for spies trying to meddle in elections or disrupt the workings of parliamentary democracy in the UK.

The Daily Mail and the Financial Times both lead with Rishi Sunak putting his concerns directly to the Chinese Premier Li Qiang at the G20 summit. The Mail's headline is "a hostile act in the heart of Parliament".

There is a growing epidemic of preventable cancers in the UK, according to the Guardian. It says researchers have put the figure for this year at 184,000. The leading causes are identified as smoking, drinking, poor diet and sunburn. The findings have prompted calls from public health campaigners for a renewed focus on the issues because of the "huge human and financial toll".

The i's top story is the prediction from its panel of experts that UK interest rate rises are set to end. The group of economists forecasts a less aggressive approach to tackling inflation, with most expecting only one more interest rate rise this year. But it describes the news as a "small mercy" for mortgage holders after 14 consecutive increases.

The Sun and the Daily Mirror both lead on dangerous dogs. "Terror on our streets" is the headline in the Mirror, which has pictures of a man being chased and attacked by a dog which it says had just mauled an 11-year-old girl in Birmingham. Noting that Suella Braverman is seeking urgent advice about banning American XL Bully dogs, the paper claims the home secretary has "finally woken up" to its campaign. The Sun makes its stance clear with the front page message "Ban XL Devil Dogs".

Several papers point out how many EU flags were being waved at the Last Night of the Proms on Saturday. The Telegraph says the BBC, which broadcast the event, is facing calls for an inquiry, and it quotes the former MP, Harvey Proctor, who describes what happened as "utterly vulgar and wrong". The Telegraph says EU flags have been given out at the Proms for several years by a pro-Remain group - Thank EU for the Music. A BBC spokesman told the paper that "audiences choose their own flags".

And the Daily Star predicts that millions of people will skip work this morning to enjoy "one last blast" of the September heatwave. The paper's headline calls it "the great British bunk off".
