But they are not recommending 'do not negotiate a preferential system' nor 'do negotiate one' (This already being misunderstood).
They are essentially silent on the negotiations. They are not privy to the UK negotiating strategy on this (partly because there isn't one yet)
"If – and this is not a MAC recommendation – immigration is not to be part of
negotiations & UK is deciding its future migration system in isolation, we recommend no preferential access"
So would be a really big failure to report correctly if broadcasters don't manage to communicate this - and so 'MAC recommends no preferences' becomes the political and public understanding
But the MAC and the media really should try to communicate accurately what it has been said and not said.
