Mayor since 2016, previously Labor MP for Tooting. Former lawyer, married with two adult daughters. Political boxer who finds it difficult to resist a verbal attack on the Tories. Often deflects criticism of his record by blaming the government. Aiming to become London's first three-term mayor.

Policy: Free school meals for primary school children

What is feasible? Introduced as a one-year “emergency measure” to ease living costs, free school meals have proven so popular that Mr Khan wants to make them permanent. What remains unsaid is that he would have faced a political backlash if he had scrapped them. But the annual cost of £140 million – which is currently being drawn upon City Hall reserves and business rates – could push up council taxes in the future.

Policy: Exclude road charges per kilometer

What is feasible? Normally, candidates are judged on what they plan to do. The row that the Tories have stirred up over the Ulez and the congestion charge potentially being replaced by a 'smart' pay-by-the-mile system is so big that Mr Khan felt obliged to make it clear that this will not come under his watch to happen. He claims Ulez's 'success' means he can meet 'net zero' targets by 2030 without having to pay per kilometer. But the impact of the expansion on air quality is still unknown, and the abolition of pay-per-mile weakens its green reputation.

Policy: Freezing of metro and bus fares

What he promises: “Freeze TfL rates until at least 2025 and continue to freeze rates as long as economic conditions allow.”
