We've been asking questions about Vijay Mallya for a very long time and not just in relation to the funding of his Formula One team, now rather less dependent on the group of companies he headed than it once was. Then again, the group isn't what it was, either, despite what it says on e.g. Expedia. Now he's been arrested, in London, the main questions are why has it taken almost a year since India cancelled his passport and asked for him to be sent back.
