Ukraine's 'Chocolate King' could edge new-look Yulia for president

KIEV (Reuters) - Gone is the trademark peasant-style hair braid, though the familiar voice and the assured, rapid-fire delivery tell you Yulia Tymoshenko is back as a political force in Ukraine.

But instead of the fiery Tymoshenko, it is Petro Poroshenko, a 48-year-old billionaire known as the 'Chocolate King' who is now the front-runner for a May 25 presidential election which the new leadership hopes will unite a divided country amid growing pressure from Russia hostile to its political changes.
