Slaughter and May and Sidley Austin have both posted 100% retention rates for their autumn intake of newly-qualified lawyers (NQs).

Slaughters is set to keep on all of its 59 trainees in September, marking an increase on recent rounds, after the firm retained 96% of its NQs in March 2011 and 93% in autumn 2010.

Sidley will also keep on all seven of its trainees this autumn, compared with a retention rate of 80% last year, when the firm offered jobs to eight out of 10 of its NQs.
