Austria’s far-right presidential candidate Norbert Hofer has said he would push for a referendum on EU membership, if the EU became more centralised after Brexit.
If Mr Hofer wins, he will become the EU’s first far-right head of state.
His independent rival, Alexander Van der Bellen, won the election in May but the vote was overturned.
The former Green party leader had beaten Mr Hofer by a margin of only 30,863 votes and Austria’s high court backed a complaint that election rules on postal voting had been broken.
Mr Hofer’s Freedom Party had argued that postal ballots were illegally and improperly handled in 94 out of 117 districts.
Although the role is largely ceremonial, the Austrian president does have the power to dissolve the lower house of parliament, the National Council, and trigger elections.
The Freedom PA told the BBC that no-one should be scared of him as a leader. However, while Muslims living in Austria were part of the country, “Islam is not part of our values”, he said.
The far-right leader has insisted that a vote for him would not be a vote for Austria pulling out of the EU, or “Oexit”.
However, he told the BBC there were two issues that might change his mind.
One was any future decision to admit Turkey into the EU. Although Turkey is in accession talks, there seems little likelihood of it joining the EU any time soon.
And then there was the EU’s response to the UK leaving the bloc.
“If the answer to Brexit would be to make a centralised European Union, where the national parliaments are disempowered and where the union is governed like a state. In this case, we would have to hold a referendum in Austria, because it would lead to a constitutional change,” he said.
