This is not an investigation, it's a parody.'He also re-christened two lavish yachts which had been named after his secretary-turned-spouse Olga Rozhkova, it is alleged. One, known as his 'love boat', was originally called St Princess Olga in her honour but was rebranded Amore Vero - or true love - after they reportedly divorced.  A steamer called Duchess Olga got the new monicker of Standard.Olga, believed to be 32, left her life at the oligarch's side for Italian racer Francesco Provenzano, leading to Sechin suing for divorce, a Russia reporter claimed.Dramatic pictures show how the 'pompous' palace was bulldozed, with an excavator stopped close to the remains of the home.Sechin, 57, a longtime Putin confidante, runs state-controlled energy giant Rosneft but has been dubbed the strongman's de facto deputy.The extraordinary claims about how he wiped Olga from his life after she fell for the 32-year-old Italian came in a 63-minute Russian online documentary and a report in independent Sobesednik newspaper.Film-maker Andrey Konyakhin said: 'Newly built buildings were falling down, the walls, floors and ceilings torn apart. It looked terrible. 'All this splendour ended up in an excavator scoop.'Asked why the designer house was trashed and not sold, he said: 'A fallout with his wife Olga apparently caused him a serious spiritual wound - so he decided to erase all memories of her.'Yacht St Princess Olga was renamed Amore Vero and Duchess Olga became Standard.'The wrecked house was on a four hectare plot longer than the Luzhniki stadium pitch where the World Cup final will be played in July, say reports.Such plots cost £37.5 million - the most expensive real estate in Russia.Nearby land is said to be registered to his two daughters Inga and Varvara, and son Ivan.Before their painful split, Olga was a regular user of the then-St Princess Olga, as shown on pictures she posted in Istagram.In 2016 she visited the Maldives, Italy, Vietnam, India, Germany and France. Favourite locations were Ibiza, Sardinia and Corsica.The couple had met when Sechin was deputy premier to Putin and she was a secretary, but were seldom seen in public together.Sechin is reported to earn £7.5 million a year, w
