Big Tech will have to follow new rules in the UK or risk facing hefty fines

Major players like Google and Facebook are set to follow new competition rules laid out by the Government.

The new Digital Markets Unit will be given powers to clamp down on “predatory practices” of some firms.

Companies can be fined 10 per cent of their global turnover if they fail to comply.

On top of that, tech firms could be handed additional penalties of 5 per cent of daily global turnover for each day an offence continues.

For companies like Apple that could be tens of billions of US dollars.

The rules also aim to give users more control over their data.

The UK Digital minister says the government wanted to “level the playing field” in the technology industry, in which a few American companies have been accused of abusing their market dominance.

Senior managers of big tech could face fines too, but right now its unclear when exactly the changes will come into force.
