After the talks, a Number 10 spokeswoman said:
David Cameron has met Gibraltar's Chief Minister Fabian Picardo at Downing Street to discuss the UK's border dispute with Spain.
- Mr Picardo's visit to the UK saw him meet with Foreign Secretary William Hague on Wednesday, a meeting he said showed that the UK and Gibraltar governments "remain in lockstep" over the disagreement.
- The spat effects regular commuters as up to 8,000 Spaniards living mainly in the nearby towns of La Linea and Algeciras travel daily to Gibraltar for work.
- Yesterday, the Gibraltar government accused Spain of introducing an export ban on construction materials to punish the enclave.
A Royal Gibraltar Police (RGP) spokesman said it received an "unofficial report" from the Guardia Civil on Wednesday about missiles being thrown at its officers from the motorcycle lane, as well as verbal abuse.
However, RGP were "unable to substantiate" accusations and continuing to investigate.
The diplomatic spat with Spain over Gibraltar takes another turn later today when David Cameron meets with Fabian Picardo, the chief minister of Gibraltar.
The Downing Street meeting comes the day after Spanish Guardia Civil officers claimed they were pelted with stones by angry commuters held at the border crossing.
Delays of several hours have continued intermittently in recent weeks, caused by stringent checks imposed by the Spanish during the diplomatic row over an artificial reef sunk off Gibraltar.
Gibraltarians claim 74 concrete blocks on the seabed were necessary for environmental reasons, but the Spanish say they disrupt an area used by fishing boats.
