A British woman is missing, feared drowned, after falling overboard a ferry.

Teresa Cowley, 43, from Derbyshire, vanished from the P&O-owned Pride of Rotterdam ferry as it travelled from Hull to the Dutch port.

She has not been seen since she walked alone to an outside deck at 1am on Friday, according to The Sun.

Ms Cowley had been drinking with her husband Mark, 43, at the ship's bar. But, when they made their way back to their cabin, the key didn't work, so Mark left Teresa outside their room as he went to for help.

According to the Mirror, CCTV footage shows Teresa, who has teenage twin girls from a previous relationship, then go alone to the 11th floor sun lounge deck.

She failed to return and was reported missing after she still wasn't found following a major search of the ship.

Derbyshire police are liaising with detectives from the Harbour Police at Rotterdam, who do not believe a criminal offence took place.
