The Government has rejected the suggestion from a committee of MPs that it needs to "get off the fence" and act more vigorously to protect British interests in Gibraltar.
A Government spokesman said: "This Government has never been on the fence when it comes to Gibraltar."
"We've been absolutely clear that we will never enter into arrangements under which the people of Gibraltar would pass under the sovereignty of another state against their wishes. And we protest each and every illegal incursion by Spanish state vessels into Gibraltar territorial waters."
