(BBC) – About 50 MPs have stormed out of Nigeria’s lower house of parliament after a motion to discuss an alleged South African arms deal was blocked.
Last week it was reported that government agents took $9.3m (£5.7m) in cash to South Africa to buy weapons.
The deputy speaker of the House of Representative said that, as it was an issue of national security, it could not be broached.
The upper chamber has also summoned security chiefs over the issue.
