Simon Mayall, former lieutenant general in the British Army, who served as the UK's defense adviser for the Middle East, on the potential use of joint base Diego Garcia and what that means for British involvement in the conflict. "The Americans have every right to use Diego Garcia", he says. "The idea that we could be a spectator in this, to my mind is fanciful", he added. Mayall speaks with Bloomberg's Guy Johnson, Kriti Gupta and Lizzy Burden on 'The Opening Trade'. (Source: Bloomberg)
