Arm co-founder partly blames ‘Brexit idiocy’ for US flotation

Hermann Hauser says UK chip designer rules could seek secondary listing in London later

Brexit idiocy" is partly to blame for Arm's decision to choose New York over London for its stock market listing, but a secondary listing in the UK at a later date would make sense, according to a co-founder of the Cambridge-based chip designer.

Arm's parent, the Japanese conglomerate SoftBank, has officially filed for a US-only listing, in a blow to the UK government, which has lobbied hard for a London listing.
