Papers probe foot-and-mouth cause

Version 0 of 1.

Speculation about who is to blame for the foot-and-mouth outbreak dominates several front pages.

"A shocking lapse in security" is the Daily Telegraph's take, after a report suggested employees at a Surrey laboratory could have been at fault.

The Daily Mail says a lab worker may have carried the virus to a vegetable patch from where it infected a farm.

As the Sun asks, did a "veggie plot" lead to the foot-and-mouth "disaster" and was it an act of sabotage?

'Livid and hurt'

Elsewhere, the papers show their support for Madeleine McCann's parents.

The Daily Mirror says the couple are "livid and very hurt" at claims in the Portuguese media that they were involved in the girl's disappearance.

"We didn't kill our Madeleine," quotes the front page of the Daily Express. "In our hearts, we know she's alive."

And the Daily Mail says the case has been "bungled from the start" and dogged by "utterly unsubstantiated insinuations" about the McCanns' role.

'Driven to death'

The Independent leads with the story of China's Yangtze river dolphin which has been declared extinct.

After 20 million years of existence, "it was driven to death by mankind" the paper laments.

The Times says the dolphin - or baiji - is the first vertebrate to become extinct for more than 50 years.

It is also the first whale, dolphin or porpoise ever to be wiped out by human influence, particularly by fishing and the destruction of its habitat.

'Seedy and costly'

The Financial Times offers hope of an end to "passenger misery" at Heathrow Airport, suggesting hand luggage restrictions are set to be relaxed.

The paper says Aviation Minister Jim Fitzpatrick is hopeful the limit of one bag per person could end by the autumn.

That news is sure to please the Daily Telegraph which says the experience of staying in the UK for holiday is often "seedy, costly and anti-child".

It says a poll of 2,000 parents rated Blackpool the worst place for a family break.
