The Managing Director of P&O Cruises has apologised after at least 300 out of 1,843 passengers on board the Oriana, fell ill during a ten day cruise through the Baltic Sea.
Carol Marlow said "We had a number of people who were taken ill. I have written to all the passengers saying how sorry I am. These are our passengers. We want them to have a good time so they sail with us again".
The company confirmed that any passengers with particular concerns might be entitled to compensation, but that this would be decided on an individual basis.
