The UK will take part in May’s European elections and British MEPs could sit for “months or even longer”, European Council President Donald Tusk has said.
Mr Tusk said the decision to delay Brexit to 31 October meant British voters would be going to the polls.
But Brexit co-ordinator Guy Verhofstadt said the six-month extension was too short for change and too far away to prompt action.
The UK PM has said she wants to leave the EU before 22 May to avoid the poll.
But Theresa May needs to get her withdrawal deal – which has been rejected three times by Parliament – approved by MPs.
Cross-party talks between the government and the Labour Party are set to resume this week to find a way through the impasse.

Meanwhile, US Speaker of the House of Representatives Nancy Pelosi has said there would be no chance whatsoever” of a post-Brexit trade deal between the US and UK if there was any weakening of the Good Friday Agreement.
The 1998 peace deal led to the end of the Troubles in Northern Ireland.
Elsewhere, in an interview with the Financial Times, Germany’s foreign minister Heiko Maas has said there will be no Brexit extension beyond October.
“They (the UK) will have to decide what they want by October,” he said. “You cannot drag out Brexit for a decade.”
Speaking in the European Parliament in Strasbourg, Mr Tusk insisted that if British MEPs were elected in May, they should be treated as “full members”.

“One of the consequences of our decision is that the UK will hold European elections next month,” he said.
“We should approach this seriously as UK members of the European Parliament will be there for several months – maybe longer.”
He said they will have “all the rights and obligations” of full members.
“I have strongly opposed the idea that during this further extension the UK should be treated as a second category member state. No, it cannot,” he said.
He said the EU had not given into “fear and scaremongering” that the UK would act in an obstructive way, saying the UK had been a “responsible and constructive member state”.
BBC Brussels correspondent Adam Fleming said this was a “clear swipe”
