Of all of this new government’s big promises, getting economic growth up and immigration down are the two biggies – and their early months in office show just how hard achieving either, let alone both, will be.
Economic growth has been stuttery and half-hearted for ages.
And immigration, both legal and illegal, via small boat crossings, has ballooned in recent years.
Now, Sir Keir Starmer and Home Secretary Yvette Cooper have reached a milestone with a big number attached.
Over the weekend, the number of people who have arrived on small boats since the general election in July exceeded 20,000.
Privately, ministers acknowledge that successfully tackling irregular, illegal migration is absolutely key to how competent or otherwise the government is perceived to be; however fair or otherwise that might be, given the scale of the challenge.
