"Opposition Labour Party plots overthrow of Capitalism" —Reuters

Note the use of the verb "to plot", which is defined by Oxford Dictionary as "a plan made in secret by a group of people to do something illegal or harmful."

It is scary: we have just discovered that there is "a plot", "a secret plan", that Corbyn, McDonnell and their guerrillas have been organising a parallel underground organisation and an armed wing of the Labour Party in order to overthrow the system, possibly with the support of Cuba and China, with promises from North Korea that she will send advisors once the new regime is estabilshed.
