By Renee Maltezou ATHENS (Reuters) - Yanis Varoufakis will not take part in "sad" elections expected next month in Greece and will instead focus on setting up a new movement to "restore democracy" across Europe, the former Greek finance minister told Reuters on Thursday. The combative, motorbike-riding academic was sacked as finance minister last month after alienating euro zone counterparts with his lecturing style and divisive words, hampering Greece's efforts to secure a bailout from partners. The one-time political rockstar has since steadily attacked the bailout programme that Prime Minister Alexis Tsipras subsequently signed up to and the austerity policies that go with it, rebelling against his former boss in parliament.
