"Our aim must be to return freedom of movement to its original intention: a right to work," Clegg wrote in the article published Tuesday.
In his article, the UK deputy prime minister also restated his idea to prevent migrants from claiming child benefits for children living outside of the UK. "As a first step, we should pay the same rate as the country in which those children reside. In the UK it is about £80 a month, whereas in Poland it is less than half that," Clegg said.
British Prime Minister David Cameron is expected to unveil his own proposals regarding benefits for new migrants later this week.
Ahead of the May 2015 national election in Britain, Cameron's Conservative party has announced it could limit immigration from other EU countries if re-elected. These plans have been criticized by EU officials as contradictory to the principle of freedom of movement.
