Newspaper headlines: IS suspect, Labour reshuffle, Channel Tunnel walker and hero aviator plane row

The life of a British man identified by security experts as the chief suspect in a new propaganda video from the Islamic State group comes under the spotlight in Tuesday's press.

The Independent reports Siddhartha Dhar, 32, a British-Indian Muslim convert, is a former bouncy castle salesman from Walthamstow, east London.

According to the Sun, Mr Dhar grew up a fan of rock band Nirvana and Arsenal football club, but "changed" following the death of his father when he was 16, and abandoned plans to become a dentist.

The key suspect in the hunt for the "new Jihadi John", says the Daily Telegraph, was able to travel to Syria with his wife and four children despite being on bail for allegedly encouraging terrorism, after he reportedly failed to hand over his passport.

But the Times says the name of the masked jihadist gunman is still a mystery after audio and video experts said Mr Dhar's accent, inflections and facial features did not match the gunman in the footage.

The Daily Mirror is among the papers to focus on the boy with a British accent who also appears in the clip. It reports on an interview a "distraught" south London man gave to the media in which he claims his five-year-old grandson is the boy in the film, having been taken to Syria by his daughter in 2013.

"My grandson doesn't know any different... He's being used," reads the Mirror's headline.

'Asserting authority'

Political correspondents offer their predictions as Labour leader Jeremy Corbyn prepares to announce details of his first shadow cabinet reshuffle.

Mr Corbyn, says the Guardian, plans to assert his authority over the divisive policy areas that have dogged his leadership. But it says there was alarm in the shadow cabinet over the suggestion he intended to "exact revenge" against MPs who voted in favour of airstrikes in Syria.

The Labour leader, it adds, wants to act with care to avoid a bloodbath and maintain his inclusive "big tent" approach to politics by shifting shadow foreign secretary Hilary Benn and shadow defence secretary Maria Eagle to other posts.

The Financial Times says Mr Corbyn's reshuffle does appear to be a shift towards a "more conventional approach to leadership".

In the Daily Telegraph Dan Hodges suggests Mr Corbyn's critics in the shadow cabinet "have been effectively neutered. They have been reminded they serve at his pleasure, and that public displays of disloyalty will no longer be tolerated."

Still, the Telegraph reports he is preparing to bow to pressure by not moving Mr Benn after being warned he could face mass-resignations.

The Independent says Mr Corbyn is also under pressure to promote more women to prominent posts in his top team.

In a leading article, the Daily Mirror urges Mr Corbyn to "try to take the party's MPs with him rather than picking ill-advised internal fights which benefit only the Conservatives".

Eye-catching headlines

'Wrong message'

The Daily Express describes a decision to grant asylum to a Sudanese man who walked through the Channel Tunnel from France to the UK as "irresponsible". Abdul Rahman Haroun, 40, was arrested after the incident in August and charged with causing an obstruction to a train but may not now face trial.

In a leading article, the Daily Mail says Mr Haroun had shown "reckless determination" in his 5,000-mile journey from war-torn Sudan. But it believes allowing him to remain in the UK "despite having entered illegally" was sending out the "wrong message".

The Daily Telegraph, meanwhile, welcomes government plans to commission the building of up to 13,000 homes on public land and set up a fund to prepare underused brownfield sites for construction. The plans address an "acute" problem, particularly in London and the South East, and could lead to "big results", it says.

The Times says the government has "taken a small step down the right path" in a strategy that could solve the "housing crisis".

But writing in the Guardian, economics commentator Aditya Chakrabortty contrasts the government pledges with its proposed changes to social housing rules. He argues the new construction plans "will make private homes even more unaffordable while cutting further the stock of homes available below market rent".

Plane 'fuss'

Finally, the Times reports plans to celebrate the achievements of Amy Johnson - the first woman to fly solo across the world from England to Australia in 1930 - are being marred by a row over a loan of her famous biplane.

The daughter of a Hull fish merchant was hailed as a national hero after her 11,000-mile journey. But the Science Museum in London is refusing to lend her De Havilland Gipsy Moth named Jason to the organisers of a festival designed to usher in Hull's reign as the UK's city of culture in 2017.

Despite an offer to cover all costs involved in dismantling and transporting the plane, the museum has expressed concerns about security and that it may not be looked after properly, says the Daily Mail.

Festival director Rick Welton tells the paper: "Given Amy Johnson flew the plane to Australia you would think we could get it 200 miles from London to Hull without all this fuss."
