Keir Starmer and Kemi Badenoch in PMQsKeir Starmer has refused to say if Labour will honour past promises not to increase taxes on working people during prime minister’s questions today.Leader of the opposition Kemi Badenoch repeatedly asked the PM if, in the government’s Budget next month, Labour would be hiking up taxes.It comes amid widespread speculation that the government will struggle to fill the growing black hole in the government finances.But Labour promised not to increase income tax, national insurance, or VAT in their election manifesto – so Badenoch asked: “Does the prime minister still stand by his promises?”“I’m glad the leader of the opposition is finally talking about the economy,” he said, before claiming retail sales are higher than expected, inflation is lower than expected, growth has been upgraded this year and the UK stock market is at “an all time high”.
