Swiss Convention on Social Security Coordination
On 9 September the UK and Switzerland signed a Convention on Social Security Coordination, which supports business and trade by ensuring that cross-border workers and their employers are only liable to pay social security contributions in one state at a time.
The Convention was published on 29 September and can be found here: -
