Thanks, Brian. As I cover the financials, references to growth are at constant exchange rates unless stated. On Slide 16, there's a summary of the group's results for the full year 2021 and I'll focus my comments on the full year performance. Turnover was £34.1 billion, up 5%, an adjusted operating profit was £8.8 billion, up 9%. Total earnings per share were 87.6p, down 13%, while adjusted earnings per share was 113.2p, up 9%. Pandemic solutions contributed approximately 9 points of growth in adjusted earnings per share. On currency, there was a headwind of 5% in sales and 11% in adjusted earnings per share, in particular, due to the strengthening of sterling against the U.S. dollar relative to 2020. Turning to the next slide. This slide summarizes the reconciliation of our total to adjusted results. The main adjusting items of note for the year were in disposals and other, which primarily reflected profits across several divestments, including the gain on disposal of rights to royalty stream for cabozantinib in Q1, the gain on disposal of the cephalosporin business in Q4 and a significant positive revaluation of deferred tax assets in the U.K. resulting from the Q2 enactment of the 2021 U.K. Finance Bill. And finally, in transaction related, the main factor was the movement on the ViiV CCL, which included the impact of the settlement with Gilead. My comments from here onwards were adjusted results unless stated otherwise. Turning to Slide 18. Key drivers of revenues and profits for the group in 2021 compared to 2020 are set out here. Revenues grew 5% overall. Revenues from our COVID solutions contributed around 4 percentage points of that growth. Positive operating leverage from higher sales in the year was supported by continued focus on cost control and the benefits and synergies resulting from restructuring across the group, with SG&A down 1%. This included favorable legal settlements compared to increased legal costs in 2020, which primarily impacted Q1 and one-off benefits in pensions and insurance in Q4. Alongside these benefits, we continue to prioritize investing in our pipeline and R&D expenditures increased by 8%. This resulted in an adjusted operating profit increase of 9%, with pandemic solutions contributing 7 percentage points of that growth. The full year margin was 25.8% and 90 basis points higher than 2020 at constant exchange rates. Turning to Slide 19. Moving to the bottom half of the P&L and highlight that the effective tax rate of 17.5% was aligned with expectations and that interest expense of £753 million was slightly lower than expected, primarily due to favorable foreign exchange. Next, I'll briefly cover free cash flow for the year before going into more detail on the financials of each business. On Slide 20, in 2021, we generated £4.4 billion of free cash flow. This was a step-down versus 2020 and consistent with our outlook given in February last year. The positive factors of increased adjusted operating profit at CER and lower dividends to noncontrolling interests were more than offset by increased purchases of intangible assets, including our collaborations with Alector and iTeos from Q3, reduced proceeds following completion of the Consumer Brands disposal program, adverse timing of returns and rebates compared to 2020 and adverse exchange impacts. Net cash generated from operations for the group was £8 billion, and we expect to share comparators for new GSK cash flow later in the first half. In 2022, we expect cash generated from operations for new GSK on a like-for-like basis to be higher than 2021 as a result of the Gilead settlement and increased adjusted operating profit. This will be partly offset by lower cash generated from lower-margin COVID solutions and headwinds related to the phasing of payments in 2021 and continued generics impact on the U.S. respiratory portfolio. Turning to performance of the Pharma business on Slide 21. Overall, Pharmaceutical revenues grew 10%, driven by strong growth in New and Specialty Medicines, favorable U.S. return on rebate adjustments and sales of Xevudy, which contributed 6 percentage points of growth. But within this 10% growth, established Pharma sales decreased 6% in 2021, which was slightly better than expected. The Pharma operating margin was 26.4% for 2021. The increase in profit margin primarily reflected the positive operating leverage from the increased sales, including favorable pricing in IRR, continued tight cost control and restructuring benefits. This was partly offset by continued investment in R&D and HIV product launches. Turning to Slide 22. Overall, vaccine sales grew [indiscernible]. Excluding pandemic adjuvant revenue, sales decreased 5%, primarily driven by Shingrix dynamics, which Luke has described. We continue to be very confident in the demand for our vaccines. Notably, during 2022, we expect Shingrix to deliver record sales with strong double-digit growth. The operating margin was 33.3%. The decrease in operating profit and margin primarily reflected higher supply chain costs resulting from lower demand. This was accompanied by an increased R&D investment of 34% as we progressed our RSV and meningitis development programs and invested in our mRNA platform. Higher royalty income and beneficial mix from pandemic adjuvant sales partly offset these factors. Q4 sales were down 7%, reflecting a tough comparison in 2020 due to strong Shingrix sales. Turning to Slide 23. Revenues in Consumer Healthcare increased 4%, excluding brands either divested or under review. Including those brands, turnover was flat. Brian outlined the main drivers earlier. The operating margin was 23.3%, up 200 basis points at CER versus last year due to sales growth, including favorable pricing and mix and strong synergy delivery. This was partially offset by a 120 basis point impact from the divested brands in addition to commodity and freight cost pressures. The strong 11% sales growth, excluding brands divestiture under review in Q4, is an encouraging sign of momentum as the business moves into 2022. Turning to Slide 24. I'll close with our guidance for new GSK in '22. 2022 also excludes the commercial impact of our COVID solutions. Our guidance is predicated on the Consumer Healthcare business being demerged in mid-2022, and we expect the formal criteria for treating Consumer Healthcare as a discontinued operation to be satisfied with Q2. GSK will continue to consolidate the business for reporting purposes until the planned demerger. As Brian mentioned earlier, the Consumer Healthcare Capital Markets Day will set out the strategic priorities, key growth drivers and detailed financial information that underpin our confidence in the compelling medium-term outlooks for that company. For new GSK, 2022, we'll see a step change in growth. We expect new GSK sales growth to be between 5% and 7% in 2022. Investments in the business for growth will continue in a focused and controlled fashion and so we expect SG&A and R&D to increase the rates similar to sales, whilst we expect cost of goods sold to increase at slower rate than sales. As a result, our guidance for adjusted operating profit is for between 12% and 14% growth. This includes the anticipated benefit of the related royalties, contributing around 2 percentage points of adjusted operating profit growth. On outlook for COVID solutions in 2022, based on known binding agreements with governments, we expect that COVID solutions will contribute a similar sales level to 2021 but substantially reduced profit contribution due to increased proportion of lower margin Xevudy sales. We expect this to reduce new GSK adjusted operating profit growth, including COVID solutions in both years, of between 5% to 7%. We'll provide quarterly updates as future contracting and binding agreements progresses. With regards to the dividend policy in 2022, the total expected cash distribution and the respective dividend payout ratios for each company are unchanged from what we communicated at our Investor Update last June. GSK expects to pay 49p per share, comprising 44 per share for new GSK and 5p per share representing Consumer Healthcare whilst still part of the group. Consumer Healthcare's dividend in the second half of 2022 is subject to review and approval by the Consumer Healthcare Board. This is expected to be around 3p per share and has been adjusted to reflect the total number of consumer shares that are expected to be an issue upon demerger and more detail is provided in the appendix. Given the complexities associated with demerging a significant operating segment of the company, we'll provide adjusted earnings per share guidance at our Q2 results following the demerger. To help with modeling new GSK, a reconciliation of the 2021 results reflect new reporting format is expected to become available later in the first half. As a reminder, we'll be presenting a single new GSK operating margin in the future. In summary, we believe the business momentum built from the excellent work for our teams in 2021 sets us up for a step change in growth from new GSK for 2022. And with that, I'll hand over to Hal.
