Saudi Arabia is considering trade sanctions against the Netherlands because of stickers printed by far-right politician Geert Wilders which display anti-Islam slogans in the colours of the Saudi flag.

Wilders, leader of the anti-immigration Dutch Freedom Party, is tied in first place with the Democrats in opinion polls ahead of Thursday's European Parliament elections.

Saudi newspaper Al Eqtisadiah reported that a directive would be circulated to authorities to exclude Dutch businesses from future projects and halt visits because of the anti-Islam statements.
