For Tony Blair, home is a messy sort of place, where the prime minister’s job is not to uphold eternal values but to force through some unpopular changes that may make the country work a bit better. The area where this is most obvious, and where it matters most, is the public services. Mr Blair faces a difficulty here which is partly of his own making. By focusing his last election campaign on the need to improve hospitals, schools, transport and policing, he built up expectations. Mr Blair has said many times that reforms in the way the public services work need to go alongside increases in cash.
Mr Blair has made his task harder by committing a classic negotiating error. Instead of extracting concessions from the other side before promising his own, he has pledged himself to higher spending on public services without getting a commitment to change from the unions. Why, given that this pledge has been made, should the health unions give ground
A. Mr Blair's unique commitment to public service reforms.
B. blank cheques given as a compromise to health workers.
C. Mr Blair's pledge to spending increases on public services.
D. pay and conditions granted to health-service workers.
