"Tobias Ellwood, the former chairman of the Commons defence committee" is about half a year behind with his accusation. So either it's just for show or he's not well informed about this topic.

Already October 2023, this was in the news for everyone to read, that France and the UK are providing the geodata for their cruise missile targets and that the UK has personnel in Ukraine.

One example article I just picked via web search: German Tagesspiegel, dated 05.10.2023

Quote & DeepL translation:

The British and French can do something "we can't"

The UK and France have nevertheless supplied cruise missiles of the virtually identical types "Storm Shadow" and "Scalp". According to Bild, Scholz said in a meeting of the Foreign Affairs Committee last week that these two countries "can do something that we are not allowed to do", adding: "So the question does not arise."

What he meant was that the UK and France supplied the geodata for missile targets themselves, with the UK also having its own personnel on the ground in Ukraine. This is out of the question for the German government.
