Following the extended weekend, the FTSE 100 saw a slight uptick on Tuesday, endeavoring to build on its longest-ever winning streak. Shares of BP climbed more than 1.5% amid reports that Shell is contemplating a potential acquisition. Shell is reportedly in consultation with advisors as it assesses BP’s share price and oil market conditions before making a final decision; despite this speculation, Shell's shares dipped approximately 1.2%. Furthermore, AB Foods saw an increase of over 1% after it confirmed negotiations to sell its Allied Bakeries division, known for its Kingsmill brand, to the private equity firm Endless. In another significant development, Deliveroo has agreed to a takeover by the American food delivery behemoth DoorDash, which values the company at £2.9 billion. Conversely, Anglo American experienced a decline of roughly 3.5%. The mining company's drop is attributed to its ongoing collaboration with Peabody to address concerns surrounding Peabody’s acquisition of its coal assets.
