The handover of the leadership was done accordingly and followed every process.
Basil welcomes Polye back and handed over the position in front of his other Opposition members this afternoon in Port Moresby.
Polye had stood down from the position after the National Court set aside his 2012 election over disputed ballot boxes.
After a successful election petition by runner-up, Alfred Manase, the court on May 2, ruled that five ballot boxes in Polye's Kandep electorate were not properly counted by the Electoral Commission.
