Corporate raider Sherborne has started to make small gains on its 5pc stake in Barclays - but stands to potentially make more if its founder Edward Bramson secures a seat on the troubled bank’s board. Sherborne stunned the City by revealing it had built a stake in Barclays worth nearly £2bn last month. The activist investor has previously used its stakes in UK firms including private equity firm Electra to oust executives and pursue drastic overhauls to drive better returns.
