Who is the Liberal Democrats' mayoral candidate Rob Blackie?

Rob Blackie is standing as the Liberal Democrat candidate in the mayoral elections.

He is a digital marketer who advises start-up tech companies.

He served as then-party leader Charles Kennedy's director of research during the Iraq War.

He will refocus police time on serious crimes

Mr Blackie's top priority as mayor is to "fix the Met".

He will prioritise funding of the Metropolitan Police, bring hundreds of officers back onto the front line and refocus officer time on serious crimes "instead of wasting time on stop and searches for low-level drug offences".

He will bring bus cuts to an end

Mr Blackie says he has a "new vision for public transport in outer London" and is committed to ending bus cuts and moving forward with the “metroisation” of key lines.

He will also invest in maintenance and accessibility upgrades on the Tube.

He will make it easier and faster for homes to be built

When it comes to housing, Mr Blackie describes himself as a "yes in my back yard" mayor and supports housing of all types and a simplification of the London Plan.

"I will create a development company to drive forward housebuilding on public land and work with local authorities to increase the number of brownfield sites allocated for development," he said.

He wants to create a visa-free travel scheme for artists

To support the cultural and creative industries in London, Mr Blackie will introduce a "London Passport" as physical proof for EU citizens, an Erasmus-style programme for young people as well as campaigning for visa-free travel for touring artists and an extension of the Youth Mobility Scheme.

He wants people to receive free energy advice to help with the cost of living

"The single biggest thing the mayor can do for Londoners on the cost of living is on housing, so my primary focus will be to increase the supply of housing," he says.

His other policies include freezing bus fares, protecting bus routes and piloting a "Green Doctor" scheme that sees experts do home visits and provide free energy efficiency advice that could reduce bills and protect the environment.
