A British tourist has been seriously injured in a car crash that killed another woman after a driver believed to be 'high on laughing gas' mounted the kerb and ploughed into a group of people in Spain.

The British woman, 23, was rushed to Ibiza's main hospital, Can Misses, after the fatal Jeep crash, which took place at 11.15am on Sunday in San Jose, a municipality on the popular party island.

Three women, described locally as 'foreigners', were walking along the pavement together when the Jeep Wrangler smashed into them near Es Pueto beach bar opposite the popular Playa des Pouet beach.

The Brit is said to be 'stable and conscious' while the nationalities of the two other women, including the one who died, are yet to be confirmed.

The other survivor, who is at a separate hospital, the Nuestra Senora del Rosario Polyclinic, is said to be 'very seriously injured' after the crash.
