Tsubaki isn't this what Tony Blair done in 1997, he changed traditional Labour policies to gain voters who wouldn't dream of voting for the Labour party, because at the time Labour was unelectable and as Blair said most of his time being a labour MP was spent in opposition. He said he/ Labour could do nothing in opposition, they needed to be in power to govern for people who had traditionally voted Labour all their lives, but we're denied a voice. So he decided to create New Labour that appealed to a greater variety of voted and New Labour went on to have their longest time I power.
So look today the Labour party have been in opposition for 14 years, isn't Starmer trying out the Blair way out of necessity ? As Blair found out then and was right Starmer is now going along the same path now, he needs to, to win the election. I know some people won't like it, but the alternative is simply another 5 years in opposition.
