Could Brexit mean that the UK will have greater freedom to offer subsidies to the private sector and to streamline public tender processes? Possibly – but perhaps not as much freedom as some have suggested.
In theory, the UK will have greater freedom to provide subsidies or other forms of state aid to UK businesses after Brexit - but the ability of the UK government and businesses to complain about state aid in rEU Member States will be diminished.
In practice, the UK's freedom for manoeuvre on state aid may be limited by its international obligations, notably under existing WTO Treaties (which it is likely to want to remain party to) and possibly also under the terms of any deal with the EU on Brexit (for example, Switzerland's agreement with the EU contains obligations relating to state aid). In the longer term, concerns have been raised that the UK's departure from the EU could result in a loosening of EU state aid policy, allowing EU member states to offer more subsidies to the private sector in future. This could leave UK firms exposed to unfair competition from EU rivals.
