Tullow Oil slips on Ugandan deal concerns, while Mauritanian well is abandoned

Two pieces of potentially bad news have sent Tullow Oil's shares sliding, making it the biggest faller in the leading index.
The exploration group is down 31p to £13.96 after Total said it was renegotiating part of a deal to buy a stake in Tullow's Ugandan oil fields.
