Local areas are among the worst in the whole of the UK for internet connectivity.
Data from the House of Commons Library shows that the Halfway, Hallside and Drumsagard area is among the worst 10 per cent across the country in terms of the number of lines receiving poor internet speed.
An alarming 25.9 per cent of lines in the area fall below 10Mpbs, while 4.4 per cent receive less than 2Mbps.
Newton Farm has long had issues with internet connectivity but this data shows that 6.7 per cent of people in this area are still unable to receive a decent broadband connection.
It places it among some of the worst connected areas in the UK.
The Vicarland and Cairns areas and the Westburn and Newton communities also fall into the worst 30 per cent of areas in the UK for line speed, with 17.6 per cent and 19.7 per cent respectively receiving less than 19MPbs.
James Kelly MSP said: “It is absolutely shocking that an area as new as Newton and Drumsagard can have such poor connectivity.
“The importance of the internet and our reliance on it in everyday lives did not come as a surprise to the developers or the council.
“These houses should never have been sold without this issue first being addressed.
“Over the past few months many people have had to work from home and have been forced to rely on the internet connections they have in their own properties.
“It’s clear that some people across Rutherglen and Cambuslang would have faced a real struggle in doing that.
“It is absolutely vital that connectivity issues are dealt with while developments are being built and not years afterwards, when they have already caused so much hassle for homeowners.
“This particular issue in Newton Farm has been ongoing for years and I have worked with both BT and the council in an attempt to address it.
“But it shouldn’t be a case of the connectivity catching up with the estate as it extends. The two things must come side by side.”
