Papa John’s, the third largest pizza delivery chain in the US, has signed an agreement with a former Burger King franchise holder to open new stores in the UK, writes The Times. Under the deal, the group plans to open at least 10 outlets along the M4 corridor over the next four years. The company, which currently operates 87 British sites, is looking to double its number of UK stores to 170 over the next three years. It has around 3,000 sites in 49 US states and 29 countries.
