Annual pre-tax losses at Posh People, owner of the Ruby in the Dust, have widened from £79,962 to £105,059 on turnover down from £2.34m to £2.23m.

The restaurant chain said gross profit margins had improved despite a difficult trading year.

It has installed electronic point of sale equipment since the end of the year and like-for-like sale in four of its five restaurants had shown an increase as well as improved overall profitability in the first quarter.

The company said its most recent purchase in Muswell Hill, London, had shown that locations outside the capital's central belt could be suitable for Ruby in the Dust
