LONDON (Reuters) - The European Union's executive arm, Ursula von der Leyne, plans to stay in a small apartment inside the headquarters of the European Commission that will lead her in the Prelemont building, a spokesman said on Thursday.

Although Von der Leyne will earn more than 25,000 euros ($ 27,000) a month, she will not rent an apartment in Brussels, instead staying in the 25-square-meter room, Bloomberg said.

The spokesman added that the move aims to avoid any additional expenses related to security measures, if rented apartment or room in a hotel, such as its predecessor Jean-Claude Juncker.

Von der Leyne will also avoid daily commute to Brussels' busy roads.

Von Der Line, the former German defense minister, is due to take office on November 1, replacing outgoing commission president Jean-Claude Juncker.

The European Commission proposes, monitors and enacts legislation on the bloc of 28 countries and other members of the European Economic Area.

It also has the power to negotiate free trade agreements and the ability to prevent mergers between giants.

Leonker has previously complained that the head of the commission is not eligible for official residence, and instead has to use his salary to secure accommodation in Brussels.

Von der Lin, a mother of seven, will keep her family's residence in Hanover, Germany, where her husband is also a doctor.

Von der Leyne, who graduated from Hanover Medical School and worked as a doctor and specializing in women's health, used to live in her office in Berlin when she was Germany's defense minister.
