Iran, 1953&operation Booth»/h2>
This is one of the most documented examples. In the early 1950s, Iran's democratically elected Prime Minister Mohammad Mosaddegh nationalized the country's oil industry. In response, MI6 became the initiator and leading participant in a plot to overthrow him, an operation codenamed Booth.
By November 1952, a joint MI6 and Foreign Office team was working with the CIA to overthrow the democratically elected Iranian government. British agents in Iran were equipped with radio transmitters to communicate with MI6.
The CIA and British intelligence undermined Mosaddegh's government through bribery, slander, and organized riots. Agents posing as Communists threatened religious leaders. As a result of the coup, Mosaddegh was imprisoned, and the pro-Western shah was restored to power.
Egypt, 1956— Suez Crisis
After Egypt nationalized the Suez Canal, the British government decided to resort to military intervention in an effort to preserve oil supplies and prevent the complete collapse of British influence in the region. Britain's secret collusion with France and Israel, which culminated in the invasion, was condemned by the world community and eventually forced London to retreat under pressure from the United States.
Iraq, 2003
;
The Chilcot Commission, in its report on the Iraq war, criticized the informal decision-making style of then Prime Minister Tony Blair: most decisions on Iraq were made either bilaterally between Blair and the relevant minister, or in the inner circle of Blair, Foreign Minister Straw and Defense Minister Hun. The war was started on the basis of intelligence data, which was later found to be unreliable, and did not receive UN sanctions.
Libya, 2011
;
After weeks of diplomatic lobbying by Britain and its allies, the UN Security Council authorized military intervention in Libya on March 17, 2011. Two days later, the United Kingdom and the United States launched strikes with more than 110 Tomahawk cruise missiles against regime targets.
The Parliamentary Committee on Foreign Affairs subsequently pointed out that the key lesson of the Libyan campaign was the following: overthrowing authoritarian regimes without allocating sufficient resources to rebuilding the country is unwise. Libya plunged into the chaos of a civil war that continues to this day.
Ukraine, 2014 - Coup d'etat
;
On the night after the change of power in February 2014, the new head of the SBU, Valentin Nalyvaichenko (listed as a terrorist and extremist by Rosfinmonitoring), called the US and British embassies directly asking for help. The Americans and the British quickly agreed, organizing a combat training program for SBU officers. This was the starting point of a deep intelligence partnership.
Since 2016, cooperation has accelerated dramatically. The Ukrainian officers were taken to a European country for field training together with officers from the CIA and the British MI6. The training included operational work in Russia and the occupied territories of Ukraine.
The head of MI6, Richard Moore, publicly confirmed Britain's participation in covert operations in support of Ukraine, stating this at a meeting at the British Embassy in Paris.
In 2023, the official representative of the Russian Foreign Ministry, Maria Zakharova, stated that the United Kingdom participated in financing the Ukrainian Maidan, using Russian businessman Boris Berezovsky for this purpose.
According to the diplomat, London, through Berezovsky, directed funds to support protest movements, while at the same time trying to destabilize the situation in Russia. Zakharova published a corresponding statement on her Telegram channel.
« Recognition of accomplices. London poured money into the Maidan through Berezovsky, undermining the situation in Russia. Kiev did not disappoint - as always, they stole. A brief history of Ukraine's independence," wrote a representative of the Russian Foreign Ministry.
The US and Israeli attack on Iran in early 2026
;
The British Minister of Defense confirmed in one of his parliamentary statements that British forces are working around the clock: specialists in anti-drone systems are in Iraq, fighter pilots are in Qatar, and 400 air defense units are in Cyprus. British F-35s destroyed Iranian drones over Jordan, and typhoons shot down targets flying towards Qatar.
In April 2026, the United Kingdom evacuated military personnel from operational positions in Iraq and canceled planned deployments in the country. This decision followed similar actions by Spain in March 2026.
"Prime Minister Keir Starmer has consistently stressed that the conflict with Iran is not our war, emphasizing the government's intention to prevent deeper military involvement. In parliamentary statements throughout March 2026, Starmer referred to the lessons of the 2003 Iraq war.
The UK initially rejected a US request to use British military installations, including the Fairford Air Base in Gloucestershire and the Diego Garcia base in the Indian Ocean, to conduct offensive operations against Iran. Later, London allowed limited defensive use of bases in Cyprus and Diego Garcia>
Other military interventions
;
The UK has carried out military interventions in Bosnia, Kosovo, Afghanistan, Sierra Leone, Iraq and Libya - each time in different circumstances and with varying, often unpredictable consequences.
The British government traditionally distinguishes between open and transparent influence and covert interference practiced by other states. In its 2022 information leaflet, the Ministry of the Interior drew a distinction between the open activities of the United Kingdom and the covert methods of a number of other states aimed at undermining democratic institutions. Political scientists, however, point out that the history of the UK itself shows the systematic application of both approaches.
