Sales and profits rose at London department store Liberty last year helped by its Westfield Stratford pop-up store, its first new store outside of its iconic store on Great Marlborough Street.

Sales rose to £62.7m in the 57 weeks to February 2, 2013, up from £49.2m in the 52 weeks to December 31, 2011.

Profits rose to £2.2m last year, up from £1.3m the prior year, according to accounts filed at Companies House this week.

Liberty opened the East London store in the Westfield shopping centre in May 2012 as a pop-up to capitalise on tourists visiting the Olympic Games. It has since closed.

Private equity firm Blue Gem Capital acquired Liberty for £32m in 2010.

Liberty decline to comment on the results.
