Reports Saudi Arabia and Russia will 'do whatever it takes' to support oil prices helps drive crude higher and push the commodities-focused FTSE 100 close to record highs, 0.28% higher to 7,456.39.
As you would expect, mining and oil stocks dominate the FTSE leaderboard.
Travel operator TUI AG (TUI) falls 5.5% to £11.25. Investors apparently unconvinced the company can grow underlying earnings 10% this year despite mounting losses in the first half.

Funeral services provider Dignity (DTY) says revenue is up by nearly 15% to £93.3m after a 7% year-on-year lift in the UK death rate in the first quarter. The high margin business reports underlying profit up 20% to £37.4m.
CCTV and surveillance minnow UniVision (UVEL:AIM) falls 20% to 3.5p as investors take profit after Friday afternoon's spectacular rally. The shares more than quadrupling after it announced a £38.1m contract with MTR Corporation in Hong Kong.
Cyber security business Sophos (SOPH) is clearly seen as a winner from the fall out of the global ransomware hacking attack, shares in the FTSE 250 business shooting 7.5% higher to 366.5p.
Elsewhere in the IT security space, recent addition to AIM ECSC (ECSC:AIM), is also soaring. Shares in the tech tiddler soar nearly 25% to 492.5p, with investors presumably assuming it too will see demand for its tools and services increase in the wake of this latest hacking attack.
