Does Tony Blair support Starmer?

My view is going to be controversial. I think Blair does support Starmer.  The intervention of Tony Blair in politics today actually raises awareness of what Starmer has done, in a way that Starmer has not been able to get across, to those on the left. 

Thanks to Blair, people have been reminded of the stance of Starmer on employment rights, net zero, the NHS and Trump. 

I do not know if this will bring back voters to Labour, notably from The Greens, but it is free publicity.
