From the UK Press Association:
“ [British] Public opinion has rallied sharply in support of the war against Iraq now British forces are in action, according to two new opinion polls. A YouGov survey for The Sunday Times found that 56% thought Britain and the US were right to take military action, with 36% opposed. The figures were almost the exact reverse of a similar poll before the outbreak of hostilities when 36% backed military action with 57% against.”
