Anti-cuts activists plan to block roads and hold street parties this weekend as part of a campaign to promote alternatives to austerity.
UK Uncut said it will target high-profile individuals they blame for the Government's spending cuts.
The group said hundreds of people will join the demonstrations on Saturday, including public sector workers, musicians and comedians.
Targets for action will include the Sheffield constituency office of Deputy Prime Minister Nick Clegg and high street stores owned by Sir Philip Green, including Top Shop and Dorothy Perkins.
UK Uncut supporter Hannah Waters said: "David Cameron has called on the country to celebrate the Jubilee with the 'mother of all our parties', while at the same time his government is cutting our welfare, our NHS, our rights; dismantling our future.
"Our street parties will bring the message home that these cuts are a political choice, a choice that is theirs, not ours, and we reject it."
