The pattern since 1997 is deepening. The 1998 Acts created the three bodies; the Welsh 2011 referendum and the Scotland Acts of 2012 and 2016 transferred steadily more power, including tax. Devolution has become a permanent, asymmetric feature of the constitution.
The 2014 independence referendum is the pivot: a 55-45 No that contained the independence pressure and was answered with the Scotland Act 2016 making Holyrood permanent. The safety valve held.
Brexit then strained the settlement. The Internal Market Act 2020 overrode devolved objections, and Stormont collapsed in 2022 before being restored in 2024 - power-sharing proving fragile but resilient.
The same events split by side. Build each paragraph around one point from each column, then judge.
The 2014 referendum cuts both ways: a No that strengthened the Union, but a 45% Yes that kept the independence question alive.
For "Evaluate the view that devolution has strengthened the Union", this timeline supplies both sides. The 1998 settlement, the 2014 No and the 2016 Act argue devolution stabilised the Union; the Internal Market Act and the Stormont collapse argue it has strained it. End each paragraph with an interim judgement.
Keep the dates precise: devolution Acts 1998, Welsh referendum 2011, Scotland Act 2012, independence referendum 2014, Scotland Act 2016, Wales Act 2017, Internal Market Act 2020, Stormont restored 2024.
