BRUSSELS, July 1 (Reuters) - Alphabet's Google

will on Tuesday warn EU antitrust regulators and its critics

that landmark European Union rules aimed at reining in Big Tech

are hampering innovation to the detriment of European users and

businesses.

The U.S. tech giant will also urge regulators to give more

detailed guidance to help it comply with the rules, and ask its

critics to provide evidence of costs and benefits to prove their

case.

Google is under pressure to address charges under the EU's

Digital Markets Act that it favours its own services such as

Google Shopping, Google Hotels and Google Flights over rivals.

The charges may result in fines of as much as 10% of its global

annual revenue.

Earlier this month, Google proposed more changes to its

search results to better showcase rival products, but critics

say these still do not ensure a level playing field.

"We remain genuinely concerned about real world consequences

of the DMA, which are leading to worse online products and

experiences for Europeans," Google's lawyer Clare Kelly will

tell a workshop organised by the European Commission to give

Google critics the opportunity to seek clarifications.

She will say changes implemented by Google to date after

discussions with the Commission and its critics have resulted in

European users paying more for travel tickets as they cannot

directly access airline sites, according to a copy of her speech

seen by Reuters.

Kelly will also say European airlines, hotels and

restaurants have reported up to a 30% loss in direct booking

traffic, while users have complained about clunky workarounds.

Google's other lawyer, Oliver Bethell, will ask regulators

to spell out in detail what the company needs to do, and critics

to come up with hard evidence.

"If we can understand precisely what compliance looks like,

not just in theory, but taking account of on the ground

experience, we can launch compliant services quickly and

confidently across the EEA," he will say.

The EEA is the 27 EU countries, Iceland, Liechtenstein and

Norway.

"We need help identifying the areas where we should focus.

That means bringing real evidence of costs and benefits that we

can take account of with the Commission," Bethell said.

The day-long workshop starts at 0700 GMT.
