Reminding ourselves that you asked to be "pointed to some (graphs predicting more than 6 months)":

It is not clear when the image in first result was published, but given that it includes error bars for dates from March 2020 onwards, I would assume this is the result of modelling performed earlier than March 2020. It covers until October 2020.

Result number two is a direct link to this paper:

https://www.imperial.ac.uk/news/196234/covid-19-imperial-res...

It was published in March 2020, and predicts data till March 2021

Result number three is a direct link to this news story (with an ironic headline, given result number 4 below):

https://www.bbc.co.uk/news/health-54831334

It was published in November 2020, and predicts data until July 2021

Result number four is a direct link to this news story:

https://www.bbc.co.uk/news/health-53392148

It was published in July 2020, and predicts data until July 2021

This is the garbage that was fed to the UK populace on a daily basis - it was like the "modellers" had taken charge.

Will you accept that graphs predicting more than 6 months of results were in common circulation?
