Question: Tesco CEO Dave Lewis  says EU exit won’t affect choice or quality but says prices are being squeezed.
 Lewis  says: “A no deal scenario  if there were to be tariffs  then actually that could impact the price of food.”
However  Tesco boss Dave Lewis admitted that the Brexit-driven collapse in the pound is pushing up prices and warned that failure to secure a deal with the EU by the March 2019 Brexit deadline could lead to higher food prices across the UK.
 Lewis  was speaking at a press conference following the release of Tesco’s half-year results  which showed sales up by 3.3% and operating profit up 27.4%. Prices rose in the period but  Lewis  was quick to point out that price rises were around 1% lower than competitors.
However  while  Lewis  disagreed with King’s assessment of Brexit   he  admitted that price rises could get worse if Britain fails to reach a deal with the EU on trading terms before the March 2019 leaving deadline.

Answer: Dave Lewis
