A UK employment tribunal has ­dismissed another case involving alleged seafarer discrimination due to a jurisdiction loophole.

British cruiseship entertainer and former X Factor TV talent show contestant James Alton claimed Royal Caribbean Group denied him a dream job after it found out about his mental health problems.

Alton took the US shipowner to an employment tribunal in November on the grounds of discrimination, seeking £32,000 ($43,100) for lost earnings, injury to feelings and aggravated damage.
