Spain defeat hands automatic qualifiation to Romania
A second guaranteed appearance in the rugby showpiece 20 years after their debut was within Spain's reach as they had routed Belgium at home earlier in the European group phase.

Social media was quick to hint at dark conspiracy theories based on the nationality - Romanian - of the referee in charge of the game.

Spanish rugby federation president Alfonso Feijoo was in no doubt where the blame lay for Spain's shock defeat.
"Everyone who has seen the game will judge the referee. He gave 10 penalties against us, the result comes from that," he posted on Twitter.
The Santiago Santos-coached side still have a chance of qualifying through the play-offs.
They next face Portugal with the winner going on to play Samoa in a two-legged play-off for a ticket to join hosts Japan, Grand Slam champions Ireland, Scotland, and the Romanians in Pool A.
Spain came unstuck against Belgium's "best possible team" according to the host side's captain Jens Torfs.
Belgian coach Guillaume Ajac, who had fielded an inexperienced team in their away tie, recalled some established stars.
