In response to Jeremy Corbyn, who said that the UK had “the slowest and most expensive broadband in the OECD, James Blessing, Chair of the Internet Services Providers’ Association said:

"Jeremy Corbyn is wrong to suggest that broadband in the UK performs poorly internationally. The OECD data clearly demonstrates that UK broadband penetration rates, prices and speeds rank highly among developed countries and the statistics have not yet recognised the significant investments from ISPA members, who use a range of technologies to deliver superfast connectivity."
