England errors aid shock Bangladesh win
England spinner Graeme Swann has been fined 10% of his match fee for showing dissent during the loss to Bangladesh.
Swann struggled in humid conditions in Chittagong and was involved in a heated exchanged with umpire Daryl Harper.
The 31-year-old pleaded guilty to using "obscene, offensive or insulting" language or gesture during a match.
The International Cricket Council said a frustrated Swann made "unacceptable" remarks, although England captain Andrew Strauss has defended his bowler.
Swann struggled to grip a ball drenched with dew during the day/night match and became irritated at the condition of the second new ball in the Bangladesh innings.
The off-spinner made the remarks during the 26th over of the World Cup match and had to be calmed down by Strauss.
"Graeme was obviously very frustrated because the dew meant he could not grip the ball," said Strauss.
Frustrated Strauss still hopeful of qualification
"He felt he had a big role to play in the game. It was frustrating for him and all of us, that the ball got as wet as it did. I told Graeme to calm down and get on with it - and he did so.
"It seems slightly strange to have the first ever day-nighter at a certain ground in a World Cup.
"There was a 20-over period when the dew was very, very bad.
"Swann could not grip the ball and I think there's something not quite right if a spinner can't grip the ball, especially in this part of the world where spin plays such an important role."
The penalty was imposed by ICC match referee Jeff Crowe, but no hearing was necessary after Swann pleaded guilty.
Crowe said: "His comments to the on-field umpires... were unacceptable and an over later Graeme, realising this, made a genuine apology to the umpires for his actions.
"While it was recognised that, because of the dew, this was a difficult period to be in the field it is also a fact that these conditions are not uncommon on the sub-continent."
Bangladesh won the match by two wickets to keep alive their hopes of reaching the quarter-final, while denting England's bid for a last eight place.
