The UK plans to revise the standards for acquiring companies, which will be a turning point for the world's fifth-largest economy, traditionally considered one of the most open markets for global mergers and acquisitions, finversia.ru writes. As a result of the most radical revision of the rules in almost 20 years, the British government will have the right to block deals in all sectors of the economy in order to prevent the transition to foreign investors of firms representing key industries. In case of adoption of new standards, the government will check annually about 50 transactions, as it was calculated in the Department for Business, Energy and Industrial Strategy of Britain.
