No other referendums are definite yet, according to the EUobserver:

Mr Fogh Rasmussen is meeting with UK prime minister Gordon Brown, who himself is also resisting domestic political pressure for an EU referendum, in London on Wednesday (10 October).

Both leaders are keenly aware that a decision to hold a referendum in either country could create a domino effect and put pressure on the other.

So far, only Ireland has said it will definitely have a referendum. The Netherlands - another country where a referendum had been a possibility - recently said it would not have a public poll.

Denmark and the UK are both countries where there is a lot of pressure to hold a referendum, but where the leaders are set against it.
