and that's it, another full toss and Cook gets down to sweep the ball to the boundary.
With that shot, Cook seals a nine-wicket win for England, as well as a 100% success record on the tour. A tired-looking Bangladesh side trudge off the field and are met at the boundary by the England squad, shaking hands to bring an end to a tour in which Bangladesh have displayed moments and sessions of brilliance, but which England never allowed to slip out of their grasp.
Apart from the final session, Bangladesh have generally looked to be positive, to their credit, and with less to lose they were often much more willing to take risks to try and force the game out of England's hands. They've not had the best of luck, with a few freakish dismissals and the odd umpiring mistake, but they haven't backed down by any means in this series, and although England have won every game of the tour the hosts have made them work hard for every win.
That'll be all from your commentary team for this series - Andrew McGlashan, Sahil Dutta and Liam Brickhill - thanks for joining us and farewell, until next time. Sahil's final bulletin of the series is up, so be sure to check that out as it's a lyrical and emotive piece of cricket literature. Thanks for all the feedback, it's been tremendous for the whole five days of this Test, and has brightened up some very early, dark and chilly starts in the Cricinfo office.
Tamim Iqbal receives the award for most valued Bangladeshi player of the series, Shakib al Hasan gets the award for Man of the Match for his scores of 49 and 96, and his four wickets. Graeme Swann gets Man of the Series for his 16 wickets.
