The UK is not alone in relying heavily on a small number of nations, especially those with relatively small populations.
The European Union is an outlier among the 28 member states in that it has a much larger number of countries with significant military and security interests.
The UK has the highest number of defence contractors, a proportion that is twice as high as the next-highest-ranked member state.
And it has the second-highest number of military-related businesses, after France, which is also home to the French Defence Ministry.
What’s more, the UK has fewer military-linked businesses than the US, Germany and Russia combined.
That may not be such a surprise given that the UK’s military spending in 2013-14 was £9.5 billion, compared with the US’s £17.7 billion, the German’s £14.4 billion and Russia’s £13.9 billion.
But the UK is also the only country that does not have a permanent presence at NATO’s HQ in Brussels.
As a result, the country’s military-services companies are often more closely linked to other countries, including the US and Germany, than they are to the UK.
In fact, the number of companies in the UK that are wholly owned by the British military has increased by nearly 30 per cent since 2013.
This is partly due to the military-industrial complex in the country.
It is estimated that between 30 and 50 per cent of UK military-supply contracts are currently awarded to foreign companies.
The Government is currently seeking to amend the Defence Act to allow the UK to compete in the European Defence Market (EDM) and in the EU’s Military and Security Market (M2M) .
But this is unlikely to happen until the new Defence Act is approved in the next parliament.
The UK’s defence-industrial links and links to other military-dependent countries have been highlighted in the 2016 Defence White Paper, which was released earlier this year.
The document lays out a number of recommendations for the Government.
Among the key points are that the Defence Industrial Strategy should be amended to allow UK companies to enter the EDM and M2M markets, and that the military should be able to use UK resources in defence projects and services, and in a “fair and balanced” way.
The Government also has set out plans to improve defence-industry links with other countries.
It has proposed that companies operating in the M2B and EDM markets would have the option to partner with firms operating in these markets.
The proposal also envisages that the Royal Navy would be able “to operate in the same areas of the European EEZ as the Royal Air Force, Royal Marines and the Royal Land Forces”.
Meanwhile, the Defence Procurement Agency (DPA) is looking to strengthen links between its military and civilian contractors.
The DPA’s new defence procurement body, the Joint Defence Procuresment Advisory Committee (JDPAC), is expected to present a range of proposals for further defence investment.
Among them are proposals to increase the DPA “ability to support military and other civilian clients in the Defence Market”.
The committee is expected also to consider increasing the DAPA’s influence over the UK Defence Procurator, the civilian arm of the DPMA, and the defence procurement process.
The Government is also considering changes to the current system of joint procurement between the UK and the EU.
Under the current rules, the EU acquires the majority of UK-built weaponry and equipment through procurement from the UK, including military hardware, vehicles and aircraft.
But it is also possible for other EU member states to buy from the British.
The proposed changes would see the UK buying parts from EU suppliers and making them available to EU firms.
These will then be sold to UK companies.
If these proposals are approved by the Government, it will likely result in a significant increase in defence spending, particularly if the UK joins the EDC.
According to the British Association for Defence and Security Research, the overall UK defence spending will rise by £6.3 billion in 2022-23.
That’s an increase of more than 20 per cent on the previous year.
In the last parliament, the British defence budget was £7.5bn, which amounted to a 5.7 per cent increase.
Although the UK spends a much smaller share of its budget on defence than other European nations, it still contributes significantly to the EU budget.
According to the DPU’s 2015 Defence Market Assessment, the total UK defence budget for the next decade is projected to be £971 billion.
What does the UK stand to gain from the Brexit deal?
While the Government has proposed the amendment of the Defence Industry Strategy to allow for joint procurement with EU companies, it has also announced that it will “pursue a strategic partnership” with the EU and the United States.
These countries are key members of the so-called
