Overview


Objectives

In a statement in September 2020, Prime Minister Boris Johnson confirmed the Integrated Review would be underpinned by a commitment to spend at least 2% of GDP on defence—as defined as a target by

and the maintenance of the British nuclear deterrent. The Prime Minister summarised the review's objectives as follows: * To define the United Kingdom's role in the world, as well as its long-term strategic aims for national security and foreign policy. * To set out how the UK will be a "problem-solving" and "burden-sharing" nation, working more effectively with its allies. * To determine the capabilities required for the next decade and beyond to pursue the UK's objectives and address the risks and threats it faces. * To address reforms to Government systems and structures to achieve these goals. * To outline the implementation for these goals and how it will be evaluated. In September 2020, Defence Secretary Ben Wallace explained that the review would deliver an armed forces that was "fit for tomorrow's battles" by switching from "traditional warfighting" to "technological warfighting". He explained that this would entail being forward deployed — for example, in

The review suffered several delays due to the

. In October 2020, the review's future came into question once again following a decision by the government to implement a separate spending review, which covered one year instead of three, due to the economic uncertainty caused by the COVID-19 pandemic. A new publication date for February 2021 was then set but was subsequently missed, due again to the pandemic. This date was then replaced by one during March.


Decisions

In November 2020, Johnson announced an investment of £16.5 billion into defence over four years — representing a share of over 2.2% of GDP — as the first conclusion of the Integrated Review. Reported as the "largest military investment in 30 years", Johnson stated: "This is our chance to end the era of retreat, transform our Armed Forces, bolster our global influence, unite and level up our country, pioneer new technology and defend our people and way of life". The investment amounts to an increase of between 10–⁠15 percent on the current annual budget of £41.5 billion. The full review, titled ''Global Britain in a Competitive Age'', was published on 16 March 2021 by the Cabinet Office. It resulted in the following notable conclusions:
