Criminal conduct

Criminal conduct

For a person to be found guilty of a criminal offence it must be shown that they:

•
acted in a particular way
•
failed to act in a particular way (omission), or
•
brought about a state of affairs.

The criminal conduct or criminal act of an offence is also known as the actus reus and this behavioural element is the essential characteristic of any offence.

Criminal act

The mental element of an offence is what a defendant must have had, while the criminal act is done or was failed to be done. When proving the required criminal act it must be shown that:

•
the defendant's conduct was voluntary, and
•
it occurred while they still had the requisite mental element

Other than in a few specific instances where an omission will suffice, the prosecution must show that the defendant acted voluntarily by operation of their own free will.

Generally, it must also be shown that the defendant had the required mental element or mens rea at the time of the carrying out of the criminal act.

CCRC refers five city traders' convictions following Supreme Court decision

The Criminal Cases Review Commission (CCRC) has referred the convictions of five city traders back to the courts. This action follows a July 2025 Supreme Court decision that quashed the LIBOR and EURIBOR convictions of Tom Hayes and Carlo Palombo. The five traders—Alex Pabon, Jay Vijay Merchant, Jonathan Mathew, Philippe Moryoussef, and Colin Bermingham—were convicted at Southwark Crown Court between 2016 and 2019 of conspiracy to defraud, receiving sentences ranging from two to eight years. The CCRC concluded that the jury misdirection and legal errors identified by the Supreme Court in the Hayes and Palombo cases similarly undermined the safety of these five convictions.

MoJ publishes 2025 Annual Prison Capacity statement showing prison system crisis averted

The Ministry of Justice (MoJ) has published its 2025 Annual Prison Capacity statement, setting out updated projections for the prison population, forecasts for prison supply and an overview of staffing and probation capacity. The statement shows that, without the Sentencing Act, which recently received Royal Assent, demand for prison places would have exceeded supply, with capacity exhausted by June 2026. The Act also makes the publication of annual prison capacity statements a statutory requirement. The government has committed £7bn over five years to deliver 14,000 new prison places by 2031, with 2,900 places already delivered since July 2024. In addition, sentencing reforms are expected to reduce projected prison population growth by 7,500 by 2028.

Spotlight on Corruption analyses police reform impact on economic crime enforcement

Spotlight on Corruption published an analysis examining government plans to establish a National Police Service (NPS), which would merge the National Crime Agency (NCA) and its economic crime units. The charity identifies potential benefits, including resolving NCA recruitment challenges, while warning of risks stemming from the proposed Home Secretary powers to direct police priorities. The analysis also notes that the NCA will not be transferred to the NPS until after the next election. This timing coincides with an upcoming FATF review of the UK and a London summit on illicit finance in June 2026.
