Erroneous announcement traced back to briefing note prepared by Treasury officals, ahead of PM’s Samoa trip

When Keir Starmer announced a shake-up in his No 10 operation last month he hoped to put an end to the missteps of his first few months in office. But an embarrassing error by Downing Street this weekend demonstrates how many pitfalls there are for a new government still learning the ropes.

In a press release on Friday, Downing Street said five new freeports would be announced in the budget. The Guardian and other outlets covered the news, which was given first to reporters who had travelled with Starmer to Samoa for the Commonwealth summit. Both the prime minister and his aides answered questions on the policy they had unveiled.
