Political activists from around the world who are planning to demonstrate against the G8 have started to arrive in Scotland. One of them is an American grandmother called Starhawk, who is going to teach her fellow protestors how to set up peaceful blockades during the summit.

A piece of wasteland in Glasgow on the proposed route of the M74 extension is being transformed into a community garden. The project's run by Dissent, a network of radical protestors who're hoping to disrupt the G8 at Gleneagles. Among them is Starhawk - a grandmother from San Franscisco and a political campaigner since the Vietnam War .

She said: "The protestors that people are so afraid of are the same people that are here building this garden. And that's why people can expect. There are people coming here to protest from all over the world, especially of course big contingents from England from Scotand from Ireland, some of the European countries. I have friends who are also coming from the United States."

Starhawk has considerable experience of non-violent direct action - peaceful protests such as road blockades. Next weekend she'll pass on her expertise in training sessions in Glasgow and Edinburgh.

She said: "We haven't actually started talking about specific plans. There's no central leadership that tells everyone go sit there, or go blockade there. Each individual groups decides what it wants to do and then we try to co-ordinate those decisions together."

Around 150 people demonstrated in Sheffield last night outside a gathering of G8 ministers - three were arrested after a minor disturbance. Thousands of protestors will soon be heading for Scotland.

Some of these people will be in the frontline next month. They say if there is trouble, the police will be to blame.

In three weeks time many of the people involved in creating the community garden will be heading to Gleneagles to protest against the G8 summit. Their message to the Scottish public - do not believe everything you read or hear about anarchists hellbent on causing trouble.
