Daniel Kretinsky (49), Czech low-key billionaire entrepreneur, whose net worth is £6bn, is the new owner of Royal Mail, the historic British company, after the £3.6bn takeover sale of its parent firm was approved by the UK Government. His EO Group is ready to make Royal Mail successful. His investments are in Eustream, Central and Eastern European energy via a labyrinthine structure of companies, which transports Russian Gas via pipelines that run through Ukraine, the Czech Republic and Slovakia.

 He build up well-known brands through Vesa Equity Investment, a private firm which is Luxembourg, also holds big stakes in Sainsbury’s and the sportwear retailer Footlocker. He owns two football club including Sparta Prague and Premier League club West Ham United, in which he holds a 27 per cent stake.

Mr Kretinsky , having studied both law and political science, is a lawyer turned entrepreneur, was born in the city of Brno in the Czech Republic.

He also owns properties in Heath Hall on London’s The Bishop Avenue- known as “Billionaires’ Row”, which he reportedly bought for £65m and once rented the property to popstar Justin Bieber for £25, 000 a week.

 He also bought a Parisian townhouse near Elysee Palace from Russian oligarch and fertiliser magnate Dmitry Rybolovlev and his ex-wife, and owns a share of the Velaa private island resort in the Maldives.

By investing in things like delivery lockers, the hope is that Royal Mail could claw back the market share it has lost in recent years and turn its fortunes around.

In October, desperate Royal Mail pushed the price for first-class mail up by 30p to £1.65, citing “very real and urgent financial challenges for the move”. Royal Mail has been fined £10.5m by the regulator Ofcom for failing to meet delivery targets for first and second class mail. Ofcom said, Royal Mail’s poor service was “now eroding public trust in one of the UK’s oldest institutions”. However, Royal Mail owner International Distribution Services (IDS) said it had carried out substantial reforms this year to try to drive improvements. Ofcom director of enforcement Ian Strawhorne said: “with millions of letters arriving late, far too many people aren’t getting what they pay for when they buy a stamp.
