Some EU countries have migration controls within single market, says MEP

The Guardian:

Vicky Ford, a Conservative MEP who chairs the European parliament’s committee on the internal market, said in one case a country had even set an “upper break” on migrant numbers without losing economic ties…

…“If you look at a country like Liechtenstein, in the EEA, they have access to free movement of goods within the single market [but they] have an absolute cap on the number of people given residency a year – and it is only 90 people,” she said…

…“Look at a country like Belgium,” she said. “To live in Brussels you need to have a social security card, you need to be registered with your local area. And you have to have an employer who is committed to pay your social security benefits – or to be able to prove that you’ve got substantial private funds.

“In practical terms it is not possible go and live in Belgium and access public services without a job … Without your social security card you can’t get housing, education, healthcare, rent a property.”

Her comments suggest that, in theory, the prime minister might not need to choose between a so-called hard or soft Brexit. But in practice European leaders do not want other countries to follow the UK’s lead so are likely to maintain their tough stance for political reasons.

This really is very odd.  Why hasn’t this been investigated by the euro-sceptic press?  Or indeed by remainers?
