David Cameron has signalled he will not be deflected from his EU referendum plans by setting out the rules that will dictate who is eligible to vote, and committing to a breakneck schedule of diplomacy to ensure his plans for significant reform in Brussels are enacted swiftly.
Downing Street has said the franchise for the referendum will be the same as that which dictates General Elections.
This means that British, Irish and Commonwealth citizens who are over 18 and resident in the UK are eligible to vote, as are UK nationals resident overseas for less than 15 years.
EU nationals resident in the UK, who are entitled to vote in European elections, will nevertheless miss out on this occasion.
An EU Referendum Bill will be the centrepiece of the Queen's Speech, to be unveiled on Wednesday.
