French owner Brittany Ferries has revealed its new $223m LNG-fueled ro-pax has been delayed at Germany's Flensburger (FSG) shipyard.

It was responding to media reports citing "financial setbacks" at the yard, according to a statement.

Brittany said FSG has made clear that these setbacks are a consequence of financial penalties imposed for late delivery of Irish Ferries' newest vessel, WB Yeats.
