International recruitment firm Michael Page made a flying start to 2011 but said profit growth in the banking sector has tailed off in the second half of the year. This announcement saw the group's share price plummet more than 12%. Revenue in the first half of 2011 rose 27.6%, or 25.8% using constant exchange rates (CER), to £502.1m from £393.5m in the first half of last year.
