A 21-year-old man has been found guilty of terrorism charges at the Old Bailey following an undercover operation by MI5.

Alfie Coleman was convicted of planning a mass gun attack after being caught in what prosecutors described as an undercover sting operation by Britain's domestic intelligence service.

During the trial, jurors heard evidence that Coleman held neo-Nazi beliefs and believed in fighting what he termed a race war. The court was presented with details of his planning activities that led to the terrorism conviction.

The case represents one of several recent prosecutions involving MI5's use of undercover operations to identify and prevent potential terrorist attacks on British soil. Intelligence services have increasingly employed such tactics to monitor and disrupt planned attacks before they can be carried out.

Coleman's conviction comes amid ongoing concerns about far-right extremism and terrorism threats in the United Kingdom. The case was heard at the Old Bailey, London's central criminal court, which regularly handles the most serious terrorism prosecutions.

Sentencing details were not immediately available following the guilty verdict.
