Dan Glass, member of the Plane Stupid (an "action" group that wanted to end airport expansion) decided to take matters into his own hands when he met UK Prime Minister Gordon Brown: he decided to glue himself to the PM!
Speaking afterwards, Mr Glass said: "My left hand was covered in superglue and I stuck it to his sleeve. "I just glued myself to him and after 20 seconds he tore my hand off - it really hurt. He had to give it a couple of tugs before it came away. "He was just grinning about it. He didn't seem to take me seriously."
After the incident Mr Glass was allowed to stay Number 10 for 40 minutes. When he left the building he tried to glue himself to the gates of Downing Street but was prevented from doing so by a police officer. "I didn't have much glue left by that point," he said.
