evidence: MPs must register their interests within 28 days of a new parliament beginning. Newly elected MPs must include any relevant interests (other than earnings) from the year prior to their election. [...] What happens if MPs fail to disclose their interests? [...] Different reporting requirements mean that ministers may occasionally make declarations on the list of ministers’ interests that are not then included in the MPs’ register, where – unlike on the ministerial list – the value of such gifts would have to be declared. Boris Johnson, for instance, recorded a free holiday on the ministerial list in 2021, but did not include the value of this on the MPs’ register, on the basis that MPs are not required to disclose gifts wholly unconnected to their parliamentary activities. 50 Walker P, ‘Johnson will not declare Spanish holiday in MPs’ register, says No10’, The Guardian, 5 November 2021, www.theguardian.com/politics/2021/nov/05/boris-johnson-will-not-declare-spanish-holiday-in-mps-register-says-no-10, retrieved 8 November 2022.
