Whilst this article doesn’t specifically mention BASEL 3, I’m getting the impression that the UK is not keen on implementing it.

LONDON (Reuters) - Britain should “go into battle” for the City of London after Brexit to strengthen its role as a globally open market that does not take rules from a “protectionist” European Union, a think-tank said in a paper published on Friday.“The City has suffered from benign neglect, and now needs the government to go into battle for it,” economist Gerard Lyons said in his paper for Policy Exchange.
The EU has said it wants reassurance that Britain won’t undercut the bloc by diverging from EU rules before granting any market access.More than 7,000 jobs have left the City for new hubs in the EU, along with trading in euro shares and derivatives, and Brussels is piling pressure on EU banks to move clearing of derivatives from London to Frankfurt.
Lyons said Britain should stand its ground in the face of the EU’s protectionist stance.
“This points to the need to diverge from the EU on financial services regulation when it suits and to make London the attractive venue for parallel markets in euro-denominated instruments,” he added.
