Amusingly, the BBC was broadcasting news about the problems on the M1.

There was a fire under an elevated section and the ferroconcrete structure is damaged.

The immediate worry is that people trying to commute into London on Monday morning may be delayed.

The BBC, once the font of proper usage, referred to the risk that "all lanes will not be open". What they meant of course is the risk that "not all lanes will be open".

It's simply failure to attend in lessons and bad grammar.
