Consequently, he could not play his customary role as the hereditary Lord High Steward of Ireland at the coronation of King Charles III.

[1] Shrewsbury joined the House of Lords when he succeeded to his father's peerages in 1980, at that time enjoying the automatic right to sit in parliament.

[8] He was largely exonerated in May,[9] when the Commissioner concluded that he was guilty of a minor breach of the peers' Code of Conduct and ordered him to write a letter of apology.

[10] In August 2022, the House of Lords commissioners for standards launched a second investigation into Shrewsbury's dealings with SpectrumX,[11] a healthcare firm that had paid him £3,000 a month between the summer of 2020 and January 2022, after leaked documents revealed that he had boasted of "very considerable" potential to open doors for SpectrumX, through what he described as his "high-level contacts".

[9] In September 2022, the Office of the Registrar of Consultant Lobbyists concluded that Shrewsbury had failed to register his company, Talbot Consulting Ltd, before contacting Lady Barran, a junior minister at the Department for Culture Media and Sport, and Alex Burghart, a junior education minister, regarding SpectrumX.

The registrar found that Shrewsbury had contravened the Transparency of Lobbying, Non-Party Campaigning and Trade Union Administration Act 2014.
