Success or failure of Starmer's promise will be difficult to measurepublished at 11:23 British Summer Time

It is not entirely clear how we will be able to tell if this plan has worked.
Keir Starmer said in his briefing: “This plan means migration will fall – that’s a promise.”
That’s not a big change from his party’s manifesto, which said: “Labour will reduce net migration."
Asked about whether this would mean a fall every year, Starmer replied: “I’m promising it will fall significantly, and I do want to get it down by the end of the Parliament significantly.”
But “significantly” is not measurable and he declined to give any actual targets, citing the failure of previous caps and quotas.
For example, in 2010 the Conservatives pledged to reduce net migration to “tens of thousands”.
The Office for Budget Responsibility, which carries out the government’s forecasts, said in March that it was expecting net migration to fall “sharply”., external
They predict a fall from 728,000 in the year to mid-2024 to 258,000 in the year to mid-2027, before rising to 340,000 in 2029-30.
