Reports today suggest that Dublin has lost out to London in the battle to secure the new European headquarters of social networking site Twitter.

Ireland had been touted as a possible location for the messaging firm’s European base but, seemingly, the company has already started recruiting in London.

According to reports today, the company has met with property agents in London and has visited locations in the west end.

Vacancies for a sales account manager, sales executive, business development mobile/electronics and communications manager, all based in London have been posted on the Twitter recruitment feed.

The European office – wherever it is – is due to open in 2012 and will focus on growing Twitter’s advertising base.

Twitter has 200 million active global users, generating 65 million tweets a day.
