Royal wedding fills front pages

Many of the Sunday papers feature pictures of Princess Anne's son, Peter Phillips, and his bride, Autumn Kelly, after their wedding in Windsor.

The Sunday Times notes that Mr Phillips has become the first of the royal family's younger generation to marry.

The Sunday Express is disapproving of the couple's decision to sell their wedding to a celebrity magazine.

Meanwhile, the Mail on Sunday goes with the headline: "The Royal Wedding...as sponsored by Hello!"

Embryo row

Battle lines are drawn in the papers as MPs prepare to vote on controversial measures in the Human Fertilisation and Embryology Bill.

Gordon Brown uses the Observer to set out his arguments in favour of the legislation that would allow scientists to create animal-human hybrid embryos.

In the Sunday Telegraph, Public Health Minister Dawn Primarolo accuses Tory MPs of trying to "hijack" the Bill by tabling amendments on abortion.

The Sunday Times reports seven ministers are expected to rebel.

By-election battle

The prime minister faces another important test this week - the Crewe and Nantwich by-election.

The Sunday Telegraph says the battle for the Cheshire seat is the most thrilling by-election for many years.

The Observer argues the loss of the seat will lead to conversations about what Labour should do with its leader.

The News of the World believes the Conservatives would see a win for them as a lucky charm. "Today: Crewe. Tomorrow: Number 10", it says.

Superbug 'breakthrough'

The news that scientists believe they have found a drug that destroys the most virulent strains of MRSA, is the Independent on Sunday's top story.

According to the paper, a study has shown that in the laboratory MRSA does not develop resistance to the drug, as it does to antibiotics.

Patients would be able to apply the drug, administered as a gel, in the nostril to protect them from infection.

The firm, Destiny Pharma, is already carrying out human trials of the gel.
