The Russia-UK story is the most consequential item for a UK-based finance professional this week. Prime Minister Andy Burnham’s decision to share classified Storm Shadow missile technology with Ukraine has prompted a direct threat from Moscow, with spokesperson Maria Zakharova warning that Britain and France are “playing with fire” and that Russia could strike military targets inside and outside Ukraine in retaliation.

Separately, Uefa is pursuing criminal proceedings against Fifa president Gianni Infantino, with the governing body also seeking documents from Joshua Kushner’s investment firm. The dispute relates to the scrapped plan to sell stakes in the World Cup. This one is unlikely to move markets directly but has implications for anyone with exposure to sports media rights or private equity vehicles with football assets.
