=== Advertising bans ===
In May 2019, TfL banned advertising from [[Saudi Arabia]], [[Pakistan]] and the [[United Arab Emirates]] due to their poor human rights records. This brought the number of countries to 11 from which TfL has banned adverts, due to them having the [[death penalty]] for homosexuals. Countries previously banned from advertising were [[Iran]], [[Nigeria]], Saudi Arabia, [[Somalia]], [[Sudan]] and [[Yemen]].<ref>{{Cite web |url = http://attitude.co.uk/article/transport-for-london-suspends-adverts-from-saudi-arabia-pakistan-and-the-united-arab-emirates-due-to-poor-human-rights-1/20864/ |title = Transport for London suspends adverts from Saudi Arabia, Pakistan and the United Arab Emirates due to poor human rights |date = 2 May 2019 |website = Attitude.co.uk |language = en-gb |access-date = 5 May 2019 |archive-date = 4 May 2019 |archive-url = https://web.archive.org/web/20190504132459/https://attitude.co.uk/article/transport-for-london-suspends-adverts-from-saudi-arabia-pakistan-and-the-united-arab-emirates-due-to-poor-human-rights-1/20864/ |url-status = live}}</ref>

In 2019, the [[Mayor of London]], [[Sadiq Khan]], introduced restrictions on advertising of unhealthy food and drinks across the TfL network. A study estimated that this led to a 7% reduction in the average weekly household purchase of foods high in fat, salt, and sugar. The largest reductions were seen in the sales of chocolate and sweets. There was no change in purchases of foods not classified as being high in fat, salt, and sugar.<ref>{{Cite journal |date = 3 August 2022 |title = Advertising ban was linked to lower purchases of unhealthy food and drink |url = https://evidence.nihr.ac.uk/alert/advertising-ban-was-linked-to-lower-purchases-of-unhealthy-food-and-drink/ |journal = NIHR Evidence |language = en-gb |doi = 10.3310/nihrevidence_52264 |s2cid = 251337598 |access-date = 16 September 2022 |archive-date = 20 September 2022 |archive-url = https://web.archive.org/web/20220920163433/https://evidence.nihr.ac.uk/alert/advertising-ban-was-linked-to-lower-purchases-of-unhealthy-food-and-drink/ |url-status = live }}</ref><ref>{{Cite journal |last1 = Yau |first1 = Amy |last2 = Berger |first2 = Nicolas |last3 = Law |first3 = Cherry |last4 = Cornelsen |first4 = Laura |last5 = Greener |first5 = Robert |last6 = Adams |first6 = Jean |last7 = Boyland |first7 = Emma J. |last8 = Burgoine |first8 = Thomas |last9 = de Vocht |first9 = Frank |last10 = Egan |first10 = Matt |last11 = Er |first11 = Vanessa |last12 = Lake |first12 = Amelia A. |last13 = Lock |first13 = Karen |last14 = Mytton |first14 = Oliver |last15 = Petticrew |first15 = Mark |date = 17 February 2022 |editor-last = Popkin |editor-first = Barry M. |title = Changes in household food and drink purchases following restrictions on the advertisement of high fat, salt, and sugar products across the Transport for London network: A controlled interrupted time series analysis |journal = PLOS Medicine |language = en-gb |volume = 19 |issue = 2 |pages = e1003915 |doi = 10.1371/journal.pmed.1003915 |issn = 1549-1676 |pmc = 8853584 |pmid = 35176022 |doi-access = free }}</ref>
