Newspaper headlines: Brexit warnings, Brussels arrest and Rolling Stones in Cuba

The debate over Britain's EU referendum is never far from the headlines - and it makes Sunday's front pages in the form of warnings against "Brexit" from Health Secretary Jeremy Hunt and US General David Petraeus.

In the Observer, Mr Hunt says people who want Britain to leave the EU must explain how they could protect the NHS from the resulting "economic shock".

He also warns that some of the 100,000 skilled EU workers in UK health and social care might leave due to uncertainty over visas and residence permits.

Matthew Elliott, chief executive of Vote Leave, tells the paper the NHS has already "plummeted into a financial crisis" under Mr Hunt, and argues a Brexit could boost health funding.

Writing in the Sunday Telegraph, Gen Petraeus, who is now retired, encourages Britons to "think twice" before voting to leave the EU, which he describes as "one of the most important institutions that undergirds Western strength".

He says he understands British "frustration" at the EU, but argues that a Brexit would "deal a significant blow to the EU's strength and resilience at exactly the moment when the West is under attack from multiple directions".

His comments will "inflame the row over whether the EU weakens or strengthens the UK's national security", the paper says, adding that a former head of MI6 and the armed forces minister believe Britain would be safer outside the union.

'Bungling Belgians'

Several papers carry news of the arrest of a suspect in Tuesday's attacks in Brussels, and the Daily Star says the man lived 500 metres from Maelbeek metro station, where one of the explosions took place.

The Sun says the suspect, arrested as he sat in a car on Thursday evening, has been charged with terror offences.

But the Sunday Times asks: "Why was vital intelligence ignored?"

It says IS "ran rings round bungling Belgians", and there has been "international fury at Belgian security lapses".

In an editorial, the paper says Belgium is the "weak link at the heart of Europe", where "jihadi enclaves" have developed.

And it agrees with comments from former PM Tony Blair, whose calls to "crush" IS and do more to tackle extremist ideologies feature on the paper's front page.

"When he says we need to step up our efforts, he is right: we cannot remain passive victims," the paper says.

Stones in Cuba

"Good evening Havana! Finally we're here," Mick Jagger told a vast crowd as the Stones finally rolled into Cuba, the Telegraph reports.

The band formed in 1962 - the same year Cuba's Fidel Castro called rock 'n' roll "the music of the enemy", Harriet Alexander writes.

But in a night many Cubans "never dared dream would be possible", the band played in front of thousands of fans - as well as "communist officials" and celebrities including Naomi Campbell and Richard Gere.

Estimates for the size of the crowd vary, but the Express says 700,000 turned out for the free show.

The band played 18 songs in a "thrilling and emotional two-hour gig", it adds.

Commenting on Jagger's performance, the Sunday People says the "wrinkly rocker gyrated in trademark style to opening number Jumpin' Jack Flash".

Minister heckled

Teachers are on "collision course" with the government after deciding to ballot for strike action over plans to make all schools into academies, the Mail on Sunday reports.

Members of the NUT voted "overwhelmingly" to reject the reform - while teachers at another union's conference gave Education Secretary Nicky Morgan a "rough ride", it says.

"Furious" NASUWT members heckled Ms Morgan and shouted "rubbish" as she gave a speech, the Mirror reports.

The papers says it was "no wonder" union members were not impressed, and says the government should listen to teachers and "let experts run schools".

The Observer says the government has "failed to learn the lesson of its expensive and damaging restructure of the health system".

"It has again been lured by the promise of ideology into a reckless, big-bang structural reform," the paper adds.
