More than £1 bn was added to the value of Tullow Oil yesterday after the exploration group announced a major find off the coast of Ghana.

The share price gushed to 935p, a rise of 183.5p over Friday's close. The 24 per cent gain is one of the biggest single-day price movements seen in a FTSE 100 company's share price without there being any M&A activity.


It came as the oil price surged to fresh highs, reaching $122 a barrel after breaching the $120 level in New York for the first time on Monday.
