"Willetts said that the UK could help to broker a deal between international powers to get the cooperation necessary for a manned mission to the Red Planet"
Well, we wouldn't want to get our hands dirty with science, manufacturing or even design, would we?
I nominate Willetts (and all the rest of the human refuse at Westminster) to be flushed down a giant toilet. Charge the public money to operate the lever, with auctioning of the rights to flush our more crooked and/or less competent politicians. That should get enough to make a dent in the national debt.
