I can't see anything about Ms May refusing to meet the VC of the Police Federation. This is the only part of the BBC live feed I can find that mentions the Police Federation
*1621: Simon Reed, Vice Chairman of the Police Federation of England and Wales reacts to Theresa May's cancelling of all police leave.
He tells BBC 5 live officers accept there is a "national emergency" and understand the nature of their job means this can sometimes happen. But, he says, many officers will be left "out of pocket" as they will not be able to go on the holiday they paid for and will not be compensated for the money lost.
Some members of the police officers have worked up to 36 hours with no rest, he adds.*
