(Reuters) - Britain's mid-cap index slid for the second straight session on Thursday after Prime Minister Boris Johnson's plan to suspend parliament raised the prospects of a no-deal Brexit, while the resulting weakness in sterling helped the exporter-heavy FTSE 100 eke out gains.
The main index <.FTSE> added 0.2%, with gains led by more internationally exposed firms such as BAT <BAT.L> and AstraZeneca <AZN.L>. The more domestically-focussed FTSE 250 <.FTMC> slipped 0.3% by 0709 GMT.
The mid-cap index was also pulled lower by a more than 17% slump in Amigo Holdings <AMGO.L> after the consumer credit provider posted lower adjusted pre-tax profit for the first quarter and cut its annual forecast.
