UK Labor Party leader Jeremy Corbyn has called on Scottish voters not to vote for Britain leaving the European Union (EU) in the hope that it would trigger second independence referendum for their country.

“I hope people will vote for what they want and decide whether they wish to be part of the European Union or not on the basis of solidarity with people across the continent,” Corbyn said during a campaign visit to the northeastern Scottish city of Aberdeen on Saturday.

“I think we should not get into that debate at the present time, the important thing is to decide how you are going to vote on 23 June,” he added, referring to the referendum on Scotland’s independence in the future.

Corbyn’s visit came after Labor party senior figures urged the party to step up its campaign to stay in the EU amid fears that Labor voters would let the UK walk towards Brexit.

“I don’t think the European Union is perfect, nobody does, I do think the working time directives, the employment rights that have been achieved by trade unions across Europe and enshrined in European law are very important,” he argued.

The UK Labor leader said a vote to remain is “not an endorsement of every bureaucratic excess of the European Union”, claiming what is important is “a principle about working with people across national borders”.

Britain will vote on June 23 on whether or not it should stay in the EU. The decision has far-reaching consequences for both the country and the bloc.

Membership of the European Union has been a controversial issue in the UK since the country joined the then European Economic Community in 1973.

Those in favor of remaining in the bloc argue that leaving it would risk the UK's prosperity, diminish its influence over world affairs, and result in trade barriers between the UK and the EU.

On the spectrum, Britons who favor withdrawal believe that outside the bloc, the UK would be better off in conducting its own trade negotiations, better able to control immigration and free from what they believe to be excessive EU regulations and bureaucracy.
