The National Security and Investment Act 2021 came into force on 4 January 2022. It is a step-change in the UK Government’s ability to scrutinise and intervene in transactions should they be deemed to be critical to national security. It significantly widens the reach of the Government’s powers, and allows for the imposition of conditions, as well as an ability to block or unwind deals. Its scope is broad and the consequences of not complying with the Act are potentially serious: they include the risk of criminal and civil proceedings.

The obligation now falls on the company to notify the Government of a potentially qualifying transaction.
During this event, our panel of speakers will answer the following questions: 

  • What transactions are covered?
  • Which industries and sectors are most at risk?
  • How does the NSIA process work and what does implementation currently look like?

The event will also look at the regime introduced by the Act and guests will have the opportunity to hear the unique insights of Lord Carlile of Berriew CBE, QC, and Will Jessett CBE. They will share their assessment of the Act to date, based on engagement across the private sector and with officials, and drawing on their own direct experiences in defining, reviewing and delivering the UK’s national security objectives. John Young will provide a brief outline of the Act, and Rebecca Niblock will consider the particular forms of criminal liability for individuals and corporates under the new legislation.

Lord Carlile is a current Member of the House of Lords, former Independent Reviewer of Terrorism Legislation (2001-2011) and former Chair of the Competition Appeal Tribunal. Will Jessett was Strategy Director at the Ministry of Defence and held various other defence and national security roles in the UK and overseas during his 33-year career. John Young is a partner in Kingsley Napley’s Corporate, Commercial & Finance Department. Rebecca Niblock is a partner and co-head of International Protection at Kingsley Napley.

The seminar will be introduced by Sophie Kemp, Head of Public Law at Kingsley Napley. Our speakers will be: 

  • Lord Alex Carlile of Berriew QC, CBE 
  • Will Jessett CBE, SC Strategy
  • John Young, Partner, Corporate and Commercial Kingsley Napley 
  • Rebecca Niblock, Criminal Litigation Partner, Kingsley Napley
