Supporters of Scottish independence could take to the streets of London as they push for a second referendum, campaigners say.
The campaign group Radical Independence Campaign is set to hold its annual conference on June 12.
It's believed it will discuss workshops on planning acts of civil disobedience to pressure the Westminster government.
A spokesman for the group said acts of civil disobedience have been touted by independence supporters before but have lacked detail, and he added protests could be held in London, or "outposts" of the UK Government - such as the Scotland Office in Edinburgh or the Faslane naval base - could be blocked.
He said: "Civil disobedience has been much discussed in the independence movement, but there's been little plan of how to take effective protest action that will have a big impact but also attract public support.
"This could mean taking to the streets of London, or blockading outposts of the UK Government.
"The Radical Independence conference will bring together people with experience of direct action to strategise how to move the discussion forward."
During the election campaign, former first minister and Alba Party leader Alex Salmond said mass protests could be a feature of negotiations with the UK Government on Scotland's independence.
The conference comes just a few months after the RIC announced it planned to dissolve.
A statement on the campaign's Twitter account in February said there were "significant differences over purpose, internal organisation and overall political strategy".
As well as organising civil disobedience, the conference will also look to "re-energise a radical grassroots movement for independence", with speakers including drugs campaigner Peter Krykant and anti-racism activist Graham Campbell.
The spokesman added: "It's undeniable there is now a clear democratic mandate for another independence referendum.
"But Boris Johnson and the UK Government are in denial and are set to continue to refuse Scotland's right to self-determination.
"Voting for independence-supporting politicians isn't going to be enough. An independence referendum can only be won by grassroots campaigning in communities.
"And another referendum will only be won if independence is seen as an opportunity for radical change, to tackle the crises of poverty, inequality and climate change."
