A man from Oxford is being held in Spain charged with helping to smuggle more than £12m of drugs into the country.

James Jansen, 36, was arrested with two other British men and a Belgian earlier this month after armed police pounced on their 36ft yacht, Sea Spirit, which was moored 20 miles off the coast of southern Spain.

The four were allegedly loading more than four tonnes of hashish from their yacht into a fast launch in preparation for taking it ashore.

Jansen and fellow Britons Daniel Webb, 32 from Peacehaven, near Brighton, and John Morgan, 36, from Greenwich, plus an unnamed Belgian are being held in jail in Murcia, in the south-east of the country.

They are in custody on the orders of a district judge after their arrests on June 5.

They will be held until their trial, which is expected to be several months away.

A Foreign Office spokesman said they were aware of the situation and were monitoring it.
