An attempt to plant a bomb in the houses of parliament was foiled by the security service (MI5) at the week end as five terrorists attempted to enter the building from the roof. The five terror suspects abseiled down the south clock face of the Westminster clock tower (Big Ben) at midday, dressed as workmen and wearing florescent green jackets.
Once they reached roof level the men striped down to black boxer shorts and bullet proof vests and ran holding the bombs down towards the house of commons.
Fortunately the security services had been notified and the men were shot from the roof using rubber bullets fired from police guns which were on-site for crowd control purposes.
The men are now being held in a secure unit awaiting trial on terrorism charges, but the closeness of this incident has raised serious issues about the level of security around Westminster palace.
It is likely that a report will have to be carried out within the next few months to find these hidden weaknesses.
