How many MSPs are also MPs?

As of my last knowledge update in October 2023, there are 12 Members of the Scottish Parliament (MSPs) who are also Members of Parliament (MPs) in the UK Parliament. This situation arises due to the dual mandate that some politicians hold, allowing them to serve in both legislative bodies. However, this practice is becoming less common as parliamentary rules and party policies evolve. For the most current numbers, it's advisable to check official parliamentary resources or recent news updates.
