To the people who were there and to the people who walked the same march around the world, I am proud of you. To the organisers of the marches all over the world, thank you. I'm going to take today to relax at home, and find a place in my room for my obscenely large placard. My fight will resume tomorrow.
We have to ensure that London keeps its place as Europe's top tech hub, to continue to be mentioned in the same breath as Silicon Valley, New York and Tel Aviv. Thinking about the unfolding legacy of UK-based startups who've hit the big time - Transferwise, Funding Circle, Deliveroo, Citymapper and ASOS, to name but a few - we mustn't miss the opportunity to continue to build on what they started.
I moved to London just over a year ago, and was introduced almost immediately to the most active and vibrant LGBT+ scene that I had ever known. People around me were comfortable in their skins in a way that was new to me - they wore the rainbow flag with pride, dated openly and flirted unashamedly.
When Donald Trump is sworn in as US President on Friday 20 January, it will be the culmination of a campaign that has traded in division and fear. In this climate of growing intolerance, it is more important than ever for those of us who believe in equality to stand up and be counted.
What does this year hold for the urban innovation agenda in the UK? Like many others, I completely failed to predict the Brexit vote or the Trump Presidency. But I'm having another go at the crystal ball gazing this year because I still think it's useful to speculate about - and prepare for - the future. So, here are my five predictions for UK cities in 2017.
With its aromatic flavours and rich spices, traditional Thai cuisine is a Londoner's favourite. From the trendy street food of East London to the authentic fine dining restaurants of the West End, South-East Asian aromas permeate the city's streets throughout the week.
Art is an essential part of our lives. Every person has their own complex opinions on it. In my experience, learning to react to it in a mature, nuanced way can have a powerful impact on how you interact with the world. Dislike is an underrated, yet crucial part of developing a sophisticated perspective.
Let's create a cycling - and pedestrian-friendly city. That doesn't mean penalising motorists, it means promoting cycling and protecting vulnerable road users so we can all get around safely. Having a transport secretary who acknowledges the right of cyclists to be on the road in the first place would be a good place to start.
To make sure the creative industries in the North can reach their potential, can face up to the challenges of Brexit in terms of skills and access to markets, we need to match the region's rich seam of talent with the right opportunities to grow and develop.
For as long as I can remember I've been going on holiday to Galloway. It's in the south west corner of Scotland - a part of the country that's often ignored as people power up the motorway to Glasgow or Edinburgh and beyond.
My recent adventures in Tower Hamlets have filled me with inspiration. Inventors Club Whitechapel looks forward to 2017 with ambitious projects to continue their mission of highlighting and nurturing young and local talent.
To save lives, but also to put London at the forefront of a clean vehicle revolution and spare its air pollution shame, the Mayor of London needs to introduce a ban on the dirtiest vehicles being used in the capital.
My innovation is called the Thames Deckway; a unique high-impact civil engineering project for smart cities - providing safe, green transport infrastructure. The Thames Deckway will create an exciting cycling experience removed from London's dangerous roads that encourages people to cycle who would otherwise not
Today we've had confirmation that a monitoring station in Brixton Road has reported that the annual legal safe levels of nitrogen dioxide were exceeded within the first five days of the year. Sadly this is no surprise to us at City Hall, and it is why our mayor, Sadiq Khan, has had to take urgent and hard-hitting measures to help halt the rise of London's filthy air pollution.
This morning Sadiq Khan issued a press release in which he made five pledges to suburban Londoners listing improvements that he claims would happen if the Government devolves control of suburban rail to Transport for London.
It is essential that the Mayor delivers on his promise to clean up London's air and that the national Government backs him. While London has the worst air pollution, this is a national problem which requires a national solution.
