György Bakondi, the prime minister's chief domestic security advisor, told public broadcaster M1 on Saturday that more and more migrants are reaching the Serbia-Hungary border, and human smugglers are constantly looking for new routes.

Last year, Hungarian border guards arrested around 900 border violators in the first four months of the year, and almost 5,000 in the same period this year, Bakondi said.

It is clear that human smugglers are watching for opportunities and regrouping their forces, for example, returning from Bosnia and Herzegovina to the Serbia-Hungary border, he said. In recent years, several countries have strengthened their borders, so illegal entry is almost exclusively possible with the help of human smugglers, "which is why this criminal business is thriving", he added.

Bakondi noted that while Spain and Italy are already trying to find a solution to the problem of illegal migration with bilateral agreements, Germany still has problems with the integration of immigrants, such as a lack of language skills and expertise. "In Sweden, where the police force is twenty-something thousand strong, there are about 60,000 immigrants in criminal gangs," he added.

He said more and more European Union member states were dissatisfied with the EU's migration policy, wanted changes, and saw the solution not in quotas, but in the firm control of external borders.
