Sir McCartney, Richard Curtis and Dua Lipa are 400 top musicians, artists and media executives who wrote to Prime Minister Sir Keir Starmer for support to protect copyright from being deprived of artificial intelligence tools.
The letter calls on Starmer to amend a bill next week to span the peer Baroness Beeban Kidron, which will provide transparency and protection for transparency and protection.
Kidron's amendment will allow tech giants to tell copyright owners that they use to train their own AI models, from music, books to movies and newspapers. This will put companies and artists “responsible for the massive theft of creative works that continue to be carried out”, the letter said.
The letter also received support from Coldplay, Sir Elton John, Russell T Davies, Antony Gormley, and senior executives from news groups such as The Telegraph and Times. The Financial Times also signed the letter.
The amendment to the Data (Use and Access) bill was defeated in the House of Commons this week, but will vote again in the House of Lords on Monday.
The government has made its own amendments that guarantee an assessment of economic impacts for different options, and the minister is retreating from the previous "first-choice" position, which would have meant that the creative industry needs to opt out of AI's work.
Officials insist that all options were on the surface after consultations on various suggestions earlier this year.
However, executives remain concerned that the technology group will eventually be allowed to cover copyright rules unless the government provides legislative support to ensure transparency and protection.
The letter warns that if artists are forced to give up their work, Britain “will lose huge growth opportunities…with its future revenue, Britain’s status as a creative power, and any hope for everyday life technology will reflect British values and laws”.
The use of data bills is the latest attempt by the creative industry to protect its copyright from being used by AI groups without attribution or payment.
Kidren said the British creative industry "must not sacrifice the interests of a few American tech companies."
She added: “The UK is a unique position to be a global player in the international AI supply chain, but grasping this opportunity requires the transparency set out in my amendment, which is crucial to creating a vibrant licensing market.”
Lord Kevin Brennan of Canton, a former MP and Labour fellow, said: “We cannot let mass copyright theft cause damage to our economy in the coming years.”
The government did not immediately respond to a request for comment.
