What the papers say - May 6

Adorable new photos of baby Prince Louis sharing a special moment with big sister Princess Charlotte feature prominently on the front pages on Sunday.

And the news that Sir Alex Ferguson has undergone emergency surgery after suffering a brain haemorrhage also dominates.

The Sunday Mirror says the football world is "in shock" after it was revealed that Sir Alex was seriously ill in hospital.

Labelling him a "Man U legend", the paper reports that the former Manchester United manager was fighting for his life.

The paper also carries a snap of Princess Charlotte tenderly kissing her three-day-old brother's forehead, captioning the photo: "Whole Lottie Love".

The picture was released by Kensington Palace and was taken by the children's mother, the Duchess of Cambridge.

The Sun also reports on Sir Alex, claiming he suffered a seizure at home.

The Sunday Times says the 76-year-old was in intensive care following the operation and claims he had been complaining of feeling ill since Thursday.

The paper also features the photo of the royal siblings.

"A kiss from big sis for little Louis", writes the Daily Mail, alongside the same image.

The paper leads on a story that claims two uncles of the new Home Secretary have been accused over a visa scam.

Elsewhere, The Observer claims that aides of Donald Trump hired an Israeli private intelligence agency to orchestrate a "dirty ops" campaign against key individuals from the Obama administration who helped negotiate the Iran peace deal.

And the Sunday Telegraph says senior figures claim Theresa May faces a revolt by the Cabinet's most senior Brexiteers if she steamrolls their objections to her favoured plans for a customs deal with the EU.

The Independent reports that Tory rebels believe they have sufficient numbers to force the PM into effectively keeping the UK in the single market.
