The Mirage IV wouldn't be a bad option, even it does have the "Not invented here and OMG you want us to buy a FRENCH plane!"
The point of departure for this option would be continued Anglo-French cooperation post Suez. As the Anglo-French cooperated with the SEPECAT Jaguar it isn't even that big a stretch.
This gives the British a supersonic medium range bomber able to carry 2 nuclear weapons which with tanker support can reach deep into the European Soviet Union, or later on with a lot of support, reach the Falklands from Ascension Island
It isn't a heavy bomber (more of a medium bomber), but not a bad option
