The Mayor of London has raised concerns that the no-fly zone over the UK could go on "for an indefinite period of time".

Speaking to World at One presenter Martha Kearney, Boris Johnson said he wanted to know whether the initial decision to stop flights at the current level of risk was correct and whether it could be revisited.

"What are we doing as an economy to prepare for what could be six months or a year, of a no-fly zone?" he said.
