Why do migrants in Calais try to reach the UK?

Boris Johnson has indicated that Government departments and agencies will get a greater say in controlling immigration numbers for their industries after Brexit.

However, Liberal Democrat home affairs spokeswoman Christine Jardine said the announcement was "nothing more than a marketing gimmick".

"Boris Johnson is showing that he fundamentally doesn't understand what makes our science sector so successful. Changing the name of a visa and removing a cap that's never been hit is not a serious plan," she said.

Ms Jardine spoke to talkRADIO's Mike Graham.
