The United Kingdom and Switzerland have signed a sweeping services trade deal that Trade Secretary Peter Kyle has called "the most significant services trade deal the UK has ever negotiated." The agreement will eliminate mobile roaming charges for tourists and business travellers crossing between the two countries, and will allow British passport holders to use automated e-gates at Zurich airport as early as the end of this year, with Geneva and Basel expected to follow. The UK government estimates the deal will boost British exports to Switzerland — already the UK's sixth-largest services export market, with over £30 billion in annual trade — by £5.2 billion per year in the long run, while also making it easier for professionals such as lawyers, accountants and architects to work in Switzerland for up to five years without stringent permit requirements.
