After a spate of ministerial scandals, Tony Blair’s government has been branded “sleazy and incompetent,” by over half those questioned in an opinion poll published today. The survey for a British newspaper also puts the prime minister’s personal ratings at their lowest level since he took over as leader of the centre-left Labour party, 12-years ago.It comes in the run-up to local elections seen as a key test of how long Blair can remain in power.His deputy John Prescott is at the centre of the latest public relations disaster – namely the publication of lurid details of an affair he has admitted to having with one of his secretarires. The married deputy prime minister, now fighting for his political life, maintains many of her allegations are untrue. Among other kiss-and-tell claims, Tracy Temple says she and her ex-boss had sex immediately after he took her to an Iraq War Memorial Service. Whatever really happened, it all deals a further hammer-blow to Labour’s hopes when England goes to the polls on Thursday.
