Unless IG follows Interactive Brokers Group, and lifts all trading restrictions in GameStop, AMC and others, my previous plan to move my £800,000+ SIPP to IG will be going to other brokers.
For those who want to trade GME stocks I can recommend DeGiro. For UK customers you will be based with an Irish account manager where the default currency is €. After changing your currency you will be able to trade in pounds.
It is an execution-only broker that charges per operation. They don't offer CFDs/Spread-betting nor ISA accounts.
They even have an API available for share dealing.
How can IG call itself a trading platform if it doesn't allow trading? Surely it is breaking the trade descriptions act, amongst many other terms and conditions. Formal complaint being made.
