Former Brazilian President Luiz Inacio 'Lula' da Silva does not seem to be phased by corruptions charges levied against him as he prepares to tour the country.<br /> He will kick off the fourth stage of the so-called 'Caravan of Hope' next Tuesday in Brazil's southern states until March 7th to whip up support for his presidential bid. <br />Lula insists he's innocent and also has his party's backing for the presidency, despite a possible ban from running in the October election.<br />He's accused of taking bribes from a construction company in exchange for government favors, along with other corruption allegations. <br />
