Blue chips are making good ground again. BG is the stand-out story of the day with another bullish update on its Brazil acreage.The group said the the test results on its 30% owned Guara discovery in the Santos Basin off the coast of Brazil were 'excellent'. The discovery, jointly owned with the operator Petrobras, which holds a 45% stake, and Repsol (25%), is estimated to contain recoverable volumes of 1.1bn to 2.0bn barrels of oil equivalent. That would dwarf the "giant" discovery announced by BP last week in Mexico. Travel groups are strong again led by Thomas Cook and British Airways.
