Boris Johnson told LBC he has doubts about a proposed red card system for blocking unwanted EU laws.
The idea is part of David Cameron re-negotiation deal with Brussels and is expected to be outlined by the EU Council president later.
The Mayor of London told Nick Ferrari he believes there is much much more that needs to be done on EU reform.
He said: "We'll have to see how it is explained to us. I haven't yet got a firm view on it. I have my doubts.
"I think what would be better would be if be had a break of our own that we were willing to use and that we were more willing to say Britain is an independent sovereign country and we don't agree with this particular piece of legislation and we want to stop it.
"That's what we should be able to do.
"David Cameron has done a very good job of negotiating at huge speed a very difficult package of measures.
"What I think everybody would want is to see more progress and let's see where we get.
"So far, I think he is doing a very, very good job of getting people to see things his way. I think there is much much more, however, that needs to be done."
