TikTok unveils European data security plan amid calls for US ban

Move comes as White House backs bill that could give it power to ban Chinese-owned app nationwide

TikTok has announced a data security regime for protecting user information across Europe, as political pressure increases in the US to ban the social video app.

The plan, known as Project Clover, involves user data being stored on servers in Ireland and Norway at an annual cost of 1.2bn (1.1bn), while any data transfers outside Europe will be vetted by a third-party IT company.
