When Boris steps down, he can threaten the RMT

There was a letter in todays Guardian which I thought amusing. Boris Johnson is trying to ban some strikes on the basis that if less than 50% of the relevant union members vote that the vote wouldn't count:

I was intrigued to read Boris Johnson's call for legislation to invalidate the results of ballots where less than half the eligible electorate exercise their right to participate (Second tube strike over job cuts hits millions of London commuters, 5 October). Presumably we can expect the resignation of the mayor of London (elected on a turnout of 45.33%) forthwith?
