Detailed account of main news story with interviews from experts and eye witnesses:

There's been a major security breach at Westminster -- environmental campaigners who are against a third runway at Heathrow Airport -- have carried out one of their most daring stunts. Five demonstrators from the campaign group Plane Stupid, climbed on to the roof of the Houses of Parliament. Our Political Correspondent, Norman Smith, reports:

Introduction from reporter on the scene:

•SMITH: Westminster may now be guarded by armed police -- but at nine thirty this morning, the five protestors managed with some ease to find their way onto one of Parliament's roofs. From there, they let down their banners, waved to the cameras - and phoned the media

Development - clips from people involved in news story:

•PROTESTOR ACT: The fact that we got in here is really not as worrying or concerning as the fact that we're on a pathway to absolute chaos if we carry on with the government's airport expansion policies.

Resolution of news story from reporter on the scene:

•SMITH: Some two hours later, they were escorted down by police and arrested.

Development - clips from people involved in news story

•MALE VOX POP 1: The whole room was shaking and vibrating, there was crashing sounds, really felt the house was coming down. I was petrified.

•MALE VOX POP 2: I just thought it was a bad dream. I were taking a funny turn. I was actually quite relieved when I found it was an earthquake.

Resolution of news story from reporter on the scene

•SIMPSON: Gainsborough has now returned to normal or has it? Experts say there's still a chance of an aftershock.
