Starmer announced he will resign as UK prime minister following a successful internal challenge, clearing the way for Andy Burnham to succeed him. Burnham, the long-serving mayor of Manchester, won a parliamentary seat last week, making him eligible to mount a leadership challenge. Starmer said his parliamentary party had answered the question of whether he remained the best person to lead into the next election and that he accepted their view. Labour leadership nominations open July 9 and the contest will be completed by Sept. 1; Starmer will remain in office until the process concludes and said he will do everything to ensure a smooth handover.

South Korea's trade minister said talks with the EU produced a positive consensus on duty-free steel import quotas. The EU will from July 1 cut annual duty-free steel imports to 18.35 mln t from 33.82 mln t (a 46% reduction) and raise tariffs on above-quota steel to 50% from 25%. Seoul is negotiating to maximize its allocation; its current duty-free quota is about 2.58 mln t. The EU has pledged any cut to South Korea's allocation will be smaller than 46% but gave no figure. The minister said South Korea made no special concessions and warned the measure violates the Korea-EU FTA and could prompt retaliatory action.
