Sega's official Olympics tie-in London 2012: The Official Videogameis the new number one in the UK all-formats software chart.
The games-buying public appears to have been inspired by Danny Boyle's opening ceremony on Friday night, propelling Sega's game to the top of the charts - and the publisher's other tie-in, Mario & Sonic At The London 2012 Olympic Games, has also profited, rising five places to number three.
It means London 2012 ends the recent chart dominance of Lego Batman 2: DC Super Heroes, which last week became the first game this year to top the chart for five consecutive weeks.
In a quiet week for new releases, there's just one new entry in the top 40: Nintendo's DS title Pokémon Conquest debuts at number 17.
