Look at the branch nodes there is some white nasty fungal thing that
goes for them during cold damp UK winters. It seldomd kills the entire
plant but it can cause pretty severe die back down one side.

Don't rip it out until the end of the season it may regrow even if it
looks totally dead for a while in the meantime. UK winters kill them if
they get wet feet, wind rocking and/or aggressive frosts

Thanks both of you. Since I am in North Wales where it is wet, windy and we
have had some presentable frosts this winter I am obviously expecting too
much of it.
I have a couple of smaller rosemary plants coming on which look okay, so as
long as they survive I will find something else to go where the big one
is/was.
