The Foreign Office lodged a formal complaint with Spain after a British diplomatic bag was opened by a Spanish border guard.
An "unlucky 13" of Britain's most wanted criminals who are thought to be hiding in Spain has been unveiled today.
A 25-year-old Spanish man living in London has been hailed as "the voice of a lost generation" after his Facebook complaint went viral.
This video is believed to show a Spanish vessel - the RV Ramon Margalef - in British waters off the coast of Gibraltar.
It was uploaded to YouTube yesterday and purportedly includes extracts of the radio conversation between the ship's skipper and Gibraltar authorities.
ITV News cannot independently confirm the veracity of this footage.
The Foreign Office has summoned Spain's ambassador to the UK over concerns regarding an "ongoing incuresion" by a Spanish vessel into Gibraltar waters.
The Minister for Europe, David Lidington, said:
Despite repeated diplomatic protests to Spain in relation to incursions into British Gibraltar Territorial Waters in recent months, a Spanish State research vessel, the RV Ramon Margalef, undertook significant surveying activity in British Gibraltar Territorial Waters on 18 and 19 November for over 20 hours. When challenged by radio, the vessel responded that it was conducting survey work with the permission of the Spanish authorities and in the interests of the European Community ...
– David Lidington, Minister for Europe
I strongly condemn this provocative incursion and urge the Spanish government to ensure that it is not repeated. We stand ready to do whatever is required to protect Gibraltar’s sovereignty, economy and security.
Authorities hunting for 13 of Britain's most wanted criminals thought to be hiding in Spain have arrested one of their targets who is a convicted sex offender.
Michael McCartney, 78, was detained in Alicante today, just hours after the list of suspects accused of attempted murder, drug smuggling and child abuse was disclosed.
McCartney, from Hertfordshire, was convicted of abusing three boys, after grooming them by buying them expensive gifts before committing the abuse.
He was found guilty of nine counts of indecent assault, indecency with a child and inciting sexual activity involving penetration in March 2013, but failed to attend court the following month for sentencing.
A National Crime Agency (NCA) spokesman said: "Acting on intelligence, officers from the Spanish National Police arrested convicted sex offender Michael McCartney at an address in Alicante at around 4.30pm."
Criminals thinking of fleeing to Spain's Costa Del Crime are being warned that Spain is "not a safe haven." The warning comes as British and Spanish authorities issue a joint list of the UK's most wanted criminals thought to be on the run in Spain. Hank Cole from the NCA said:
Spain is not a safe haven. Fifty three fugitives have been caught since Captura was launched, and many more linked to other operations.
The most important thing though is the power of this campaign to harness the eyes and ears of the public, both here and in Spain.
A list of 13 British criminals wanted in Spain will be unveiled under a joint operation by Crimestoppers, the UK's National Crime Agency (NCA) and Spanish police, in the eighth appeal of its kind run under Operation Captura.
The initiative, targeting criminals thought to have fled to Spain, was launched in 2006 and so far has seen 53 out of 63 suspects caught. Founder of Crimestoppers Lord Ashcroft said:
Despite our success so far, there are still a number of dangerous criminals who see Spain as a safe haven to hide from their past. But with the support of the Spanish and UK public, we can hunt them out and bring them to justice.
Authorities in Spain are due to release an "unlucky 13" list of Britain's most wanted criminals thought to be hiding in the country later today.
The list includes the suspected leader of a £90 million cocaine smuggling ring.
Ian Stanton, 42, from Liverpool, is accused of being the ringleader of a gang who smuggled more than 400kg of cocaine to the UK hidden in a shipment of Argentinian beef.
He has links to Merseyside - specifically Crosby, Kirkby and Maghull - but also with London, the Netherlands and Spain.
The drugs were found at Tilbury docks in Essex in May, and the shipment was due to be delivered to a cold storage company in Wigan.
A minute's silence has been held at the Japanese Grand Prix in memory of the Formula One test driver Maria De Villota.
F1 drivers staged the tribute before the race. Maria De Villota's been described as an inspiration and leading light for women in motorsport.
Yesterday the Spanish test driver's family issued a statement saying that she died as a result of injuries she suffered after a crash in Cambridgeshire last year. Her body was found at a hotel in Spain on Friday.
Maria de Villota's family have said the Formula One driver died as a direct consequence of the testing accident she was involved in last year.
A statement issued by the family read: "Maria left us while she was sleeping as a consequence of the neurological injuries she suffered in July of 2012, according to what the forensic doctor has told us."
De Villota lost her right eye in the incident at Duxford Aerodrome 15 months ago, but following a month's recuperation in hospital she made a remarkable recovery.
The body of the former Marussia test driver, who was 33, was discovered at a hotel in Seville early yesterday.
Doctors later confirmed De Villota's death "was due to natural causes".
María de Villota's manager, Mark Blundell, believes that the Spaniard would have been "the next female Formula One driver".
De Villota was found dead in a hotel room in Seville earlier this morning.
The 33-year-old's racing career was cut tragically short when she lost an eye in an accident at Cambridgeshire's Duxford Aerodrome last year.
However, Blundell believes that De Villota had the talent to become the first female driver to enter the Formula One World Championship since Giovanna Amati back in 1992.
