The British Government should increase the Royal Navy's presence in Gibraltar in response to Spanish incursions into its territorial waters, Chief Minister Fabian Picardo has said.
Mr Picardo said the latest alleged incursion - a Spanish research vessel ignoring requests to leave the territory's waters for 20 hours - was a "security issue that Spain needs to be aware of".
He told BBC Radio 4's Today programme that he was "in favour of anything that has a positive deterrent effect" but that "diplomatic aspects must be equally important".
The Foreign Office has accused a Spanish survey ship of acting unlawfully and provocatively by sailing into British waters around Gibraltar.
This evening it responded by summoning the Spanish Ambassador - for the third time in two years - to explain the alleged incursion.
ITV News Europe Correspondent Emma Murphy reports:
A spokesman for the Ministry of Defence (MoD) has said that the Royal Navy took "proportionate responses" after a Spanish vessel allegedly entered British waters off the coast of Gibraltar:
The Ramon Margalef, a Spanish State oceanographic survey ship, entered British Gibraltar Territorial Waters on the evening of Monday 18 November and unlawfully conducted survey operations for 22 hours in violation of United Nations Convention on Law of the Sea (UNCLOS).
The RN Gibraltar Squadron's Fast Patrol Boats HMS Sabre and HMS Scimitar, in accordance with UNCLOS, challenged the Ramon Margalef's presence by issuing appropriate warnings and preventing the deployment of the Ramon Margalef's oceanographic surveying probe.
– MoD spokesman
There was no damage to any Royal Navy or Spanish equipment or vessels and no injuries were incurred.
The actions of the Royal Navy were fully in accordance with Her Majesty's Government's commitment to uphold the sovereignty of Gibraltar with a range of proportionate responses.
This is the third time the Spanish Ambassador has been publicly summoned in relation to Gibraltar since the current Spanish government took office in December 2011.
An MP raised the issue of the alleged incursion by a Spanish vessel into British waters in a Westminster Hall debate earlier today, describing it as "a very serious incident".
Labour MP Jim Dobbin asked: "Is a minister from the Foreign Office coming to make a statement on what is a very, very serious incident?"
Deputy Speaker Lindsay Hoyle replied: "I've been given no notification of a statement to be made but I'm sure the Foreign Office is listening very carefully to what you've just said on such a serious incident."
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.
