The number of Czechs opposed to siting a radar in their country as part of a US missile defence shield has risen to nearly two thirds, according to a poll published on Thursday. Some 65 percent of Czechs are opposed to the tracking radar, according to the CVVM poll of 1,013 people between June 4 and 11, up from 61 percent in a similar poll in May. Forty percent of those questioned in the latest survey said they were "decisively opposed" to installing the US radar in their country, compared to only six percent who said they were "decisively in favour" of the move.
